Alcohol from sawdust detailed production technology. Production of ethyl alcohol from sawdust

Sawdust is a valuable raw material for the production of various alcohols that can be use as fuel.

Such biofuels can run:

automobile and motorcycle gasoline engines;
power generators;
household gasoline equipment.

Main problem one that has to be overcome in the manufacture of biofuels from sawdust is hydrolysis, that is, the conversion of cellulose into glucose.

Cellulose and glucose have the same basis - hydrocarbons. But for the transformation of one substance into another, various physical and chemical processes are necessary.

The main technologies for converting sawdust into glucose can be divided into two types:

industrial requiring sophisticated equipment and expensive ingredients;
homemade that do not require any sophisticated equipment.

Regardless of the method of hydrolysis, sawdust must be crushed as much as possible. For this, various crushers are used.

How smaller size sawdust, topics more efficient there will be a decomposition of wood into sugar and other components.

You can find more information about sawdust grinding equipment here:. No other preparation of sawdust is required.

industrial way

Sawdust is poured into a vertical hopper, then filled with sulfuric acid solution(40%) in a ratio of 1:1 by weight and, having closed hermetically, is heated to a temperature of 200–250 degrees.

In this state, sawdust is kept for 60–80 minutes, constantly stirring.

During this time, the process of hydrolysis takes place and cellulose, absorbing water, breaks down into glucose and other components.

The substance obtained as a result of this operation filter, obtaining a mixture of glucose solution with sulfuric acid.

The purified liquid is poured into a separate container and mixed with a solution of chalk, which neutralizes acid.

Then everything is filtered and get:

toxic waste;
glucose solution.

Flaw this method in:

high requirements for the material from which the equipment is made;
high costs for acid regeneration,

therefore it was not widely used.

There is also a less expensive method., in which a solution of sulfuric acid with a strength of 0.5–1% is used.

However, effective hydrolysis requires:

high pressure (10–15 atmospheres);
heating up to 160-190 degrees.

The process time is 70–90 minutes.

Equipment for such a process can be made from less expensive materials, because such a dilute acid solution is less aggressive than that used in the method described above.

A pressure of 15 atmospheres is not dangerous even for conventional chemical equipment, because many processes also take place at high pressure.

For both methods use steel, hermetically sealed containers up to 70 m³, lined with acid-resistant bricks or tiles from the inside.

This lining protects the metal from contact with acid.

The contents of the containers are heated by supplying hot steam into them.

A drain valve is installed on top, which is adjusted to the required pressure. Therefore, excess steam escapes into the atmosphere. The rest of the steam creates the necessary pressure.

Both methods involve the same chemical process.. Under the influence of sulfuric acid, cellulose (C6H10O5)n absorbs water H2O and turns into glucose nC6H12O6, that is, a mixture of various sugars.

After purification, this glucose is used not only to obtain biofuels, but also for the production of:

drinking and technical alcohol;
Sahara;
methanol.

Both methods allow you to process wood of any species, therefore they are universal.

As a by-product of processing sawdust into alcohol, lignin is obtained - a substance that sticks together:

pellets;
briquettes.

Therefore, lignin can be sold to enterprises and entrepreneurs who are engaged in the production of pellets and briquettes from wood waste.

Another a by-product of hydrolysis is furfural. It is an oily liquid, an effective wood preservative.

Furfural is also used for:

oil refining;
purification of vegetable oil;
plastics production;
development of antifungal drugs.

In the process of processing sawdust with acid toxic gases are released, That's why:

all equipment must be installed in a ventilated workshop;
workers must wear safety goggles and respirators.

The yield of glucose by weight is 40–60% of the weight of sawdust, but taking into account the large amount of water and impurities the weight of the product is several times greater than the initial weight of the raw material.

Excess water will be removed during the distillation process.

In addition to lignin, the by-products of both processes are:

alabaster;
turpentine,

which can be sold for some profit.

Purification of glucose solution

Cleaning is carried out in several stages:

Mechanical cleaning using a separator removes lignin from the solution.
Treatment chalky milk neutralizes the acid.
settling separates the product into a liquid solution of glucose and carbonates, which are then used to obtain alabaster.

Here is a description of the technological cycle of wood processing at a hydrolysis plant in the city of Tavda (Sverdlovsk Region).

home method

This method is easier but takes an average of 2 years. Sawdust is poured in a large pile and watered abundantly with water, after which:

cover with something
leave spitting.

The temperature inside the heap rises and the process of hydrolysis begins, as a result of which cellulose is converted to glucose which can be used for fermentation.

The disadvantage of this method The fact is that at a low temperature the activity of the hydrolysis process decreases, and at a negative temperature it completely stops.

Therefore, this method is effective only in warm regions.

Besides, there is a high probability of degeneration of the hydrolysis process into decay, because of which it will turn out not glucose, but sludge, and all cellulose will turn into:

carbon dioxide;
a small amount of methane.

Sometimes in houses they build installations similar to industrial ones. . They are made of stainless steel, which can withstand the effects of a weak solution of sulfuric acid without consequences.

Heat up the content such devices with:

open fire (bonfire);
stainless steel coil with hot air or steam circulating through it.

By pumping steam or air into the container and monitoring the readings of the pressure gauge, the pressure in the container is regulated. The hydrolysis process starts at a pressure of 5 atmospheres, but proceeds most efficiently at a pressure of 7–10 atmospheres.

Then, just as in industrial production:

purify the solution from lignin;
processed with a solution of chalk.

After that, the glucose solution is settled and fermented with the addition of yeast.

Fermentation and distillation

For fermentation into glucose solution add regular yeast that activate the fermentation process.

This technology is used both in enterprises and in the production of alcohol from sawdust at home.

Fermentation time 5–15 days, depending on the:

air temperature;
types of wood.

The fermentation process is controlled by the amount of formation of carbon dioxide bubbles.

During fermentation, such a chemical process occurs - glucose nC6H12O6 breaks down into:

carbon dioxide (2CO2);
alcohol (2C2H5OH).

After the end of fermentation material is distilled- heating to a temperature of 70–80 degrees and cooling the exhaust steam.

At this temperature evaporate from the solution:

alcohols;
ethers,

while water and water-soluble impurities remain.

steam cooling;
alcohol condensation

use a coil immersed in cold water or cooled by cold air.

For strength increase the finished product is distilled 2-4 more times, gradually lowering the temperature to a value of 50-55 degrees.

The strength of the resulting product determined with an alcohol meter which estimates the specific gravity of a substance.

The product of distillation can be used as a biofuel with a strength of at least 80%. A less strong product has too much water, so the technique will work inefficiently on it.

Although the alcohol obtained from sawdust is very similar to moonshine, its cannot be used for drinking due to the high content of methanol, which is a strong poison. In addition, a large amount of fusel oils spoils the taste of the finished product.

To clean from methanol, you must:

the first distillation is carried out at a temperature of 60 degrees;
drain the first 10% of the resulting product.

After distillation remain:

heavy turpentine fractions;
yeast mass, which can be used both for the fermentation of the next batch of glucose, and for the production of fodder yeast.

They are more nutritious and healthy than the grain of any cereal crops, so they are readily bought by farms that breed large and small livestock.

Biofuel application

Compared to gasoline, biofuels (alcohol made from recycled waste) have both advantages and disadvantages.

Here Main advantages:

high (105-113) octane number;
lower combustion temperature;
lack of sulfur;
lower price.

Due to the high octane number, increase compression ratio, increasing the power and efficiency of the motor.

Lower combustion temperature:

increases service life valves and pistons;
reduces engine heat in maximum power mode.

Due to the absence of sulfur, biofuels does not pollute the air And does not shorten engine oil life, because sulfur oxide oxidizes the oil, worsening its characteristics and reducing the resource.

Due to the significantly lower price (except for excises), biofuel saves the family budget.

Biofuels have flaws:

aggressiveness towards rubber parts;
low fuel/air mass ratio (1:9);
weak evaporation.

biofuel damage rubber seals, therefore, during the conversion of the motor to run on alcohol, all rubber seals are changed to polyurethane parts.

Due to the lower fuel-to-air ratio, normal biofuel operation requires reconfiguration of the fuel system, that is, installing larger jets in the carburetor or flashing the injector controller.

Due to low evaporation Difficulty starting a cold engine at temperatures below plus 10 degrees.

To solve this problem, biofuels are diluted with gasoline in a ratio of 7:1 or 8:1.

To run on a mixture of gasoline and biofuel in a ratio of 1: 1, no engine modification is required.

If there is more alcohol, then it is desirable:

replace all rubber seals with polyurethane;
grind the cylinder head.

Grinding is necessary to increase the compression ratio, which will allow realize higher octane. Without such alteration, the engine will lose power when alcohol is added to gasoline.

If biofuels are used for electric generators or household gasoline appliances, then it is desirable to replace rubber parts with polyurethane ones.

In such devices, head grinding can be dispensed with, because a small loss of power is compensated by an increase in fuel supply. Besides, need to reconfigure the carburetor or injector, any specialist in fuel systems can do this.

For more information about the use of biofuel and the alteration of motors to work on it, read this article (Application of biofuel).

conclusions

Production of alcohol from sawdust - difficult process, which includes a lot of operations.

If there are cheap or free sawdust, then by pouring biofuel into the tank of your car, you will save a lot, because its production is much cheaper than gasoline.

Now you know how to get alcohol from sawdust used as biofuel and how you can do it at home.

Also, did you know about by-products that arise during the processing of sawdust into biofuels. These products can also be sold for a small but still profit.

Thanks to this, the biofuel business from sawdust is becoming highly beneficial, especially if you use fuel for your own transport and do not pay excise duty on the sale of alcohol.

Siberian scientists are working on a technology for the production of domestic bioethanol

In Soviet times, who still remembers, they joked a lot about alcohol made from sawdust. There were rumors that after the war, cheap vodka was made just on the basis of "sawdust" alcohol. In the people, this drink was called - "bitch".

In general, talk about the production of alcohol from sawdust arose, of course, not from scratch. Such a product was actually produced. It was called "hydrolytic alcohol". The raw material for its production was indeed sawdust, more precisely, cellulose extracted from the waste of the forestry industry. Speaking strictly scientifically - from non-food plant materials. According to rough calculations, about 200 liters of ethyl alcohol could be obtained from 1 ton of wood. This supposedly made it possible to replace 1.5 tons of potatoes or 0.7 tons of grain. Whether such alcohol was used in Soviet distilleries is unknown. It was produced, of course, for purely technical purposes.

It must be said that the production of technical ethanol from organic waste has long excited the imagination of scientists. You can find literature of the 19th century, where the possibilities of obtaining alcohol from a wide variety of raw materials, including non-food ones, are discussed. In the 20th century, this theme sounded with renewed vigor. In the 1920s, scientists in Soviet Russia even suggested making alcohol from… feces! There was even a playful poem by Demyan Bedny:

Well the time has come
Every day is a miracle:
Vodka is driven from shit -
Three liters per pood!

Russian mind will invent
To the envy of all Europe -
Soon the vodka will flow
Into the mouth from the very ass ...

However, the idea with feces remained at the level of a joke. But cellulose was taken seriously. Remember, in The Golden Calf, Ostap Bender tells foreigners about the recipe for "stool moonshine". The fact is that with cellulose they were already “chemizing” at that time. Moreover, it should be noted that it can be extracted not only from the waste of the forest industry. Domestic agriculture annually leaves huge mountains of straw - this is also an excellent source of cellulose. Do not waste good. Straw is a renewable source, one might say - free.

There is only one catch in this case. In addition to the necessary and useful cellulose, the lignified parts of plants (and straw is one of them) contain lignin, which complicates the whole process. Due to the presence of this very lignin in the solution, it is almost impossible to obtain a normal “mash”, since the raw material is not saccharified. Lignin inhibits the development of microorganisms. For this reason, “feeding” is required - the addition of normal food raw materials. Most often, this role is played by flour, starch or molasses.

Of course, you can get rid of lignin. In the pulp and paper industry, this is traditionally done chemically, such as by acid treatment. The only question is where to put it then? In principle, good solid fuel can be obtained from lignin. It burns well. Thus, the Institute of Thermal Physics of the Siberian Branch of the Russian Academy of Sciences has even developed an appropriate technology for burning lignin. But, unfortunately, the lignin that remains from our pulp and paper production is unsuitable as a fuel due to the sulfur it contains (the consequences of chemical processing). If we burn it, we get acid rain.

There are other ways - to process raw materials with superheated steam (lignin melts at high temperatures), to carry out extraction with organic solvents. In some places they do just that, but these methods are very costly. In a planned economy, where all costs were borne by the state, it was possible to work in this way. However, in a market economy, it turns out that the game, figuratively speaking, is not worth the candle. And when comparing costs, it turns out that the production of industrial alcohol (in modern terms, bioethanol) from traditional food raw materials is much cheaper. It all depends on how much you have such raw materials. Americans, for example, have an overproduction of corn. It is much easier and more profitable to use the surplus for the production of alcohol than to transport it to another continent. In Brazil, as we know, surplus sugarcane is also being used as feedstock for the production of bioethanol. In principle, there are not so few countries in the world where alcohol is poured not only into the stomach, but also into the tank of a car. And everything would be fine if some well-known world figures (in particular, the Cuban leader Fidel Castro) did not oppose such an “unfair” use of agricultural products in conditions when in some countries people suffer from malnutrition, or even die of hunger. .

In general, meeting philanthropic wishes, scientists working in the field of bioethanol production should look for some more rational, more advanced technologies for processing non-food raw materials. Approximately ten years ago, specialists from the Institute of Solid State Chemistry and Mechanochemistry of the Siberian Branch of the Russian Academy of Sciences decided to take a different path - to use the mechanochemical method for these purposes. Instead of the well-known chemical processing of raw materials or heating, they began to use special mechanical processing. Why special mills and activators were designed. The essence of the method is as follows. Due to mechanical activation, cellulose passes from the crystalline state to the amorphous state. This makes it easier for the enzymes to work. But the main thing here is that the raw material in the process of mechanical processing is divided into various particles - with different (higher or lower) lignin content. Then, thanks to the different aerodynamic characteristics of these particles, they can be easily separated from each other using special devices.

At first glance, everything is very simple: grind - and that's it. But only at first glance. If everything was really so simple, then in all countries they would grind straw and other plant waste. In fact, it is necessary to find the right intensity here so that the raw material is separated into individual tissues. Otherwise, you will end up with a monotonous mass. The task of scientists is just to find the necessary optimum here. And this optimum, as practice shows, is quite narrow. You can also overdo it. That, I must say, is the work of a scientist in order to reveal the golden mean. Moreover, here it is necessary to take into account economic aspects - namely, to work out the technology so that the costs of mechanochemical processing of the feedstock (however cheap it may be) do not affect the cost of production.

Dozens of liters of wonderful alcohol have already been obtained in laboratory conditions. The most impressive thing is that alcohol is obtained from ordinary straw. And - without the use of acids, alkalis and superheated steam. The main help here is the “miracle mills” designed by the specialists of the Institute. In principle, nothing prevents us from moving on to industrial designs. But that is another topic.

Here it is - the first domestic bioethanol from straw! Still in bottles. Will we wait until they start producing it in tanks?

How to get alcohol or other liquid fuel from sawdust?

in Germany at the end of World War II, all tanks went to synthetic. sawdust fuel. and cars in Brazil drive very much on alcohol, 20% of the cars there are on alcohol. so it’s true, you can use fermentation, overtake and get alcohol and you will have a car
maybe you can get methane with the help of bacteria? even better then
I'll share my experience, so be it! In general, you take 1KG. you dry wood sawdust or other things very carefully, then add electrolyte (sulfuric acid) 1/3 of the volume to the flask or something else through the refrigerator (there will be sublimation). you heat it up to a temperature of 150 degrees, and you get Methyl Alcohol, and in the same place its esters, etc. COMBUSTIBLE reaction products. liquid can be of different colors. but usually bluish, volatile. Yes, when you cook, do not forget to add pieces of Corundum (aluminum oxide) - this is a catalyst. as soon as the liquid in the vessel or flask turns black, to the point of being unrecognizable, change and fill in the next portion. with 1 kg you will get somewhere 470 ml. alcohol, but only 700 something. Do it in an open area, well ventilated and away from food. Yes, don't forget your mask and respirator. Strain the black (spent) liquid, and the top layer burns very well after drying. add it to the fuel too.
From conifers - bad. Typically, hydrolysis alcohol is obtained from hardwoods. Here, in fact, there are two options, and both are practically not implemented at home. And stool vodka is by and large a joke, since production is inefficient and the use of the final product can be hazardous to health. First option. It is necessary to put the sawdust in a fairly large pile on the street, wet it with water and leave it for a couple of years (precisely two years or more). Anaerobic microorganisms will settle in the center of the heap, which will gradually carry out the breakdown of cellulose to monomers (sugars), which can already be fermented. Further - as usual moonshine. Or the second option, which is implemented in industry. Sawdust is boiled with a weak solution of sulfuric acid at elevated pressure. In this case, the hydrolysis of cellulose is carried out in a few hours. Next - distillation as usual.
If we consider not only ethyl alcohol, then we can go a different way, but, again, it is practically not realized at home. This is the dry distillation of sawdust. The raw material must be heated in a sealed container to 800-900 degrees. and collect escaping gases. When these gases are cooled, creosote (the main product), methanol and acetic acid condense. Gases are a mixture of various hydrocarbons. The rest is charcoal. It is this kind of coal in the industry that is called charcoal, and not from a fire. It used to be used in metallurgy instead of coke. After its additional processing, activated carbon is obtained. Creosote is the resin used to tar sleepers and telegraph poles. Gas can be used as ordinary natural gas. Now liquids. Methyl, or wood, alcohol is distilled off from the liquid at temperatures up to 75 degrees. It can pass for fuel, but the yield is small and it is very poisonous. Next is acetic acid. When neutralized with lime, calcium acetate is obtained, or, as it was previously called, gray wood acetic powder. When it is calcined, acetone is obtained - why not fuel? True, now acetone is obtained in a completely synthetic way.
Looks like I didn't forget anything. Well, when do we open a creosote shop?
"And if vodka was not driven from sawdust, then what would we have, from five bottles?" (V.S. Vysotsky)

There is a growing demand for biofuels - combustible liquids made from renewable biological resources. One of them is wood. Is it possible to obtain fuel from wood that is not inferior to oil?

The first thing to understand is that it is precisely gasoline or kerosene that cannot be made from wood. It does not decompose into straight chain hydrocarbons, of which petroleum products are mainly composed. However, this does not mean that substances that can replace petroleum products cannot be obtained from it.

Some people love the stool

First on the list, of course, is alcohol. Two different types of alcohol can be obtained from wood. The first, which is called woody, is scientifically methyl alcohol. This substance is very similar to the usual ethyl alcohol, both in combustibility and in smell and taste. However, methyl alcohol differs in that it is very poisonous, and ingestion of it can lead to fatal poisoning. At the same time, it is a high-quality motor fuel, its octane number is even higher than that of ethyl alcohol, and much higher than that of ordinary gasoline.

The technology for obtaining methyl alcohol from wood is very simple. It is obtained by dry distillation, or pyrolysis. More precisely, it is one of the components of the liquid - a mixture of oxygen-containing organic substances that are separated from freshly expelled wood resin. However, the yield of alcohol thus obtained is too low to be used as a fuel. This makes this technology of fuel production unpromising.

However, ethyl alcohol can also be obtained from wood, in much larger quantities. This alcohol - the so-called hydrolysis - is obtained by the decomposition of cellulose, the main component of wood, with the help of sulfuric acid. Rather, when cellulose decomposes, sugars are obtained, which in turn can be processed into alcohol in the usual way. This method of obtaining ethyl alcohol is very common in industry; it is the hydrolysis method that produces almost all technical alcohol used for non-food purposes.

Ethyl alcohol can be used both directly instead of gasoline and as an additive to gasoline. By means of such additives, various grades of biofuels are obtained, which are popular, in particular, in countries such as Brazil.

Obtaining ethyl alcohol by hydrolysis of wood is somewhat less economically profitable than obtaining it from various agricultural crops. However, the advantageous side of this method of obtaining biofuel is that it does not require the allocation of agricultural areas for "fuel" crops that do not provide food products, but allows the use of forestry areas for its production. This makes the production of biofuel ethanol from wood a rather practical technology.

And turpentine is good for anything

The disadvantage of ethanol as a fuel is its low calorific value. When used in engines in its pure form, it gives either less power or more consumption than gasoline. Mixing alcohol with substances with a high calorific value helps to solve this problem. And not necessarily these are products from oil: turpentine, or turpentine, is quite suitable as such an additive.

Turpentine is also a product of wood processing, and more specifically, coniferous: pines, firs, larches and others. It is widely used as a solvent, and its most purified varieties are used in medicine. However, the timber processing industry produces a large amount of the so-called sulfate turpentine as a by-product - the lowest grade containing toxic impurities, not only inapplicable in medicine, but also finds very limited use in the chemical and paint and varnish industries.

At the same time, turpentine of all wood processing products is most similar to an oil product, more precisely, to kerosene. It has a very high calorific value and can be used as fuel in kerosene stoves, lamps, and kerosene gases. It is also suitable as a motor fuel, however, for a short time: if it is poured into tanks in its pure form, the engines soon fail due to tarring.

However, turpentine can be used as a fuel not in its pure form, but as an additive to ethanol. Such an additive does not greatly reduce the octane number of ethyl alcohol, but increases the heat of combustion. Another positive side of this biofuel manufacturing technology is that turpentine denatures alcohol, making it unsuitable for ingestion as alcohol. And the social consequences of the widespread introduction of undenatured alcohol as a fuel can become very severe.

Lignin waste - into income!

Such a component of wood as lignin is considered of little use. Its use in industry is much less widespread than that of cellulose. Despite the fact that it finds application in the production of building materials and in the chemical industry, more often it is simply burned directly at the timber and chemical industry. However, as it turns out, more diverse products can be obtained from lignin pyrolysis than from cellulose pyrolysis.

Lignin consists mainly of aromatic rings and short straight hydrocarbon chains. Accordingly, during its pyrolysis, predominantly hydrocarbons are obtained. However, depending on the pyrolysis technology, it is possible to obtain both a product with a high content of phenol and related substances, and a liquid resembling petroleum products. This fluid is also suitable as an ethanol additive for biofuel production.

Technologies and installations for pyrolysis have been developed that can consume both lignin from dumps and wood waste not separated into lignin and cellulose. Better results are obtained when mixing lignin or wood waste with garbage consisting of discarded plastic or rubber: the pyrolysis liquid is more oily.

Peaceful atom and sawdust

Another technology for obtaining biofuel from wood was developed quite recently by Russian scientists. It belongs to the field of radiochemistry, that is, chemical processes occurring under the influence of radioactive radiation. In the experiments of scientists from the Institute of Chemistry. Frumkin's sawdust and other wood waste were subjected to simultaneous exposure to strong beta radiation and dry distillation, and the heating of the wood was carried out precisely with the help of super-strong radiation. Surprisingly, under the influence of radiation, the composition of the products obtained during pyrolysis has changed.

In the pyrolysis liquid obtained by the "radioactive" method, a high content of alkanes and cycloalkanes, that is, hydrocarbons contained mainly in oil, was found. This liquid turned out to be much lighter than oil, comparable, rather, with gas condensate. Moreover, the examination confirmed the suitability of this liquid for use as a motor fuel or processing into high-quality fuels, such as motor gasoline. We think that this does not deserve special mention, but let's clarify for the sake of calming the fears of radiophobes: beta radiation is not capable of causing induced radioactivity, therefore the fuel obtained in this way is safe and does not exhibit radioactive properties itself.

What to recycle

It is clear that it is preferable to use not whole tree trunks for biofuel production, but wood processing waste, such as sawdust, wood chips, twigs, bark, and even the same lignin that goes to dumps and furnaces. The output of these wastes per hectare of felled forest is, of course, lower than wood in general, but we should not forget that they are obtained as a by-product in the production processes that are already underway at many enterprises in the country, respectively, production wastes are cheap and for them there is no need to cut down or plant additional forest areas for felling.

In any case, wood is a renewable resource. Ways to restore forest areas have long been known, and in many regions of the country there is even an uncontrolled overgrowth of abandoned agricultural land with forests. One way or another, the Russian Federation is not one of the countries where forest conservation should be treated with all due diligence; the areas of our forest and its potential for self-restoration are quite enough to fully load the timber processing industry, the production of biofuels, and many other industries.

Today, quite a lot of people are engaged in the manufacture of homemade liqueurs, however, some drinks require the presence of an alcohol element. The production of alcohol at home is not very laborious. To do this, you need to know and take into account some aspects and principles for the manufacture of methyl alcohol.

First of all, the presence of grain is required for the manufacture of methanol. In the role of grain crops in this case, corn, wheat can act. You can also use potatoes and starch. But, as you know, in interaction with a substance, starch does not give any reaction. In order to produce a chemical element, the sugaring method is used. And in order to sugar it, certain enzymes are needed, they are present in the malt. By making ethanol from grain without chemical impurities, the yield of a natural product is observed.

Methanol production technology

The technology for the production of an alcohol chemical at home can consist of several stages.

Below are the most basic ones:

Methanol production with malt. Grains of cultivated plants must be germinated in small dishes, while they are scattered in one layer, up to about three centimeters. Remember that pre-sprouted grains must be treated with a solution of potassium permanganate. After processing, the seeds are placed in a container and moistened with water. It should be borne in mind that the presence of sunlight, or the sufficiency of light, directly depends on the rate of grain germination. A polyethylene material or thin glass should be covered over the container, that is, it should be sufficiently transparent. If there is a decrease in the amount of water, it must be added.
Next step: starch processing. To begin with, we extract starch from the product that is selected for the manufacture of ethanol. In this case, it's potatoes. Slightly spoiled potatoes must be boiled until a paste begins to form from the water. Next, we wait until the product has cooled down, in the meantime we grind the malt. Next, mix the two products. Next, the starch splitting procedure takes place, it must be carried out at a temperature of at least 60 ˚ C. Now the mixture is placed in a bowl with hot water and left for 1 hour. After the time has elapsed, the product is completely cooled.
fermentation stage. As you know, fermentation is characterized by the presence of alcohol containing elements. However, it is impossible to call Braga an alcoholic drink. After the mixture has cooled, yeast is added, which can react even at room temperature. However, if the temperature rises higher, the fermentation of the product will naturally occur faster. With significant heat, the fermentation procedure will end after three days. At the same time, a mild smell of grain can be felt from the product.
The next step is distillation. With what is it produced? For this, a special apparatus for the production of alcohol at home is used.
The final stage is the purification technology. We can say that methyl alcohol is ready, but it is noticed that the liquid is not transparent. That is why cleaning is done. It is carried out by adding a solution of potassium permanganate. In this form, we leave methyl alcohol for one day, then filter it - the product is ready.

As you can see, the technology for making homemade alcohol is quite simple and does not require additional effort.

Production of ethanol substance from sawdust

In recent years, fossil raw materials that can be used to make ethyl alcohol have significantly decreased. There is a shortage of grain. However, the production of alcohol from sawdust is not the worst option, since this raw material is constantly updated over the years.

However, the manufacture of the substance from sawdust requires some skills, and in addition, the manufacturer must have special equipment, without which it will be laborious to produce ethanol. The production of alcohol from sawdust at home is very popular, so it does not require high costs.

As you know, your own manufactured ethanol is not compared with the factory version. Products made in economic conditions are of higher quality, because each ingredient is distinguished by its uniqueness. It is much easier to produce alcohol from sawdust!

How to produce an alcoholic product at home?

The production of ethyl alcohol at home is carried out using a special apparatus. This device is able to carry out the procedure for the splitting of certain elements, as well as to carry out chemical reactions between them. Ordinary equipment for the manufacture of alcoholic beverages may look like mini factories. You can make any kind of alcoholic beverages in them.

It is quite simple to study the technology for the preparation of ethyl substance, while the product is of high quality. What can be obtained from this? Firstly, these are high-quality alcoholic products, and secondly, their own costs are fully recovered, this requires a special apparatus.

For example, if sugar is used in an amount of 20 kg, up to 12 liters of alcohol come out of it. The percentage of methanol reaches up to 96%. From this calculation, 25 half-liter bottles of vodka come out. In addition, the electricity that the device consumes will be spent about 25 kW.

Such equipment is capable of using all loaded products for their intended purpose. The undrinkable product yield from the first treatment can be used as a cleaner for glass surfaces and windows. Also, such a device can be installed independently, using the necessary diagrams and drawings. Such equipment can easily cope with the production of methyl alcohol.

Equipment for the production of alcoholic products has some principles of its work. The device has a special neck that fills the tank with the necessary liquid. Braga can act in the form of such a liquid. With the help of heating burners, the product is heated to the boiling point. After that, the apparatus and equipment must be transferred to normal mode.

Further, cooling takes place through the refrigeration compartment with additional purification of steam from unnecessary impurities. The purified substance enters the tank, and the vapors enter the refrigerator, where they are cooled to a liquid state. The apparatus for the production of alcohol is able to develop the established standard. The result of this procedure is alcohol of high quality preparation.
