Free gasoline do at home yourself!
Guidance for the manufacture of small-sized apparatus for home-made 100% gasoline substitute of any brand of water and domestic gas entering the apartment, as well as a description of its technology.
The liquid obtained using this description is methanol (methyl alcohol).
Pure methanol is used as a solvent and as a high-octane additive to motor fuel, as well as the most high-octane (octane number is 150) gasoline. This is the same gasoline, which is filled with tanks of racing motorcycles and cars. As shown by foreign studies, the engine running on methanol, serves many times longer than when using conventional gasoline, its power increases by 20% (with a constant working volume of the engine). The exhaust of the engine operating on this fuel is environmentally friendly and when tested for toxicity there are practically no harmful substances.
Small-sized apparatus for obtaining this fuel is simple to manufacture, does not require special knowledge and scarce parts, trouble-free operation.
Its performance depends on various reasons, including the size.
The apparatus, scheme and description of the assembly of which we bring to your attention, at D = 75mm gives three liters of finished fuel per hour, has a weight of about
Warning: methanol is a strong poison. It is a colorless liquid with a boiling point of 65 ° C, has an odor similar to that of ordinary drinking alcohol, and is mixed in all respects with water and many organic liquids. Remember that 30 milliliters of drunk methanol is deadly !
The principle of operation and operation of the apparatus
Tap water is connected to the “water inlet” (15) and, passing on, it is divided into two streams: one stream through the faucet (14) and the hole (C) enters the mixer (1), and the other stream through the faucet (4) and hole (G) goes to the refrigerator (3), passing through which water, cooling the synthesis gas and gasoline condensate, leaves through the opening (S).
Domestic natural gas is connected to the gas inlet pipeline (16). Next, the gas enters the mixer (1) through the hole (B), in which, mixed with water vapor, is heated on the burner (12) to a temperature of 100-120 ° C. Then from the mixer (1) through the hole (D) the heated mixture of gas and water vapor enters through the hole (B) into the reactor (2). The reactor (2) is filled with catalyst No. 1, consisting of 25% nickel and 75% aluminum (in the form of chips or in grains, industrial grade GIAL-16). In the reactor, the formation of synthesis gas occurs under the influence of temperature from 500 ° C and higher, obtained by heating the burner (13). Next, the heated synthesis gas enters through the opening (E) into the refrigerator (W), where it must be cooled to a temperature of 30-40 ° C or lower. Then the cooled synthesis gas through the hole (I) comes out of the refrigerator and through the hole (M) enters the compressor (5), which can be used as a compressor from any domestic refrigerator. Next, compressed synthesis gas with a pressure of 5-50 through the opening (H) exits the compressor and through the opening (O) enters the reactor (6). The reactor (6) is filled with catalyst No. 2, consisting of chips of 80% copper and 20% zinc (ICI composition, brand SNM-1 in Russia). In this reactor, which is the most important component of the apparatus, synthesis gasoline vapor is formed. The temperature in the reactor should not exceed 270 ° C, which can be controlled by a thermometer (7) and adjusted with a faucet (4). It is desirable to maintain the temperature in the range of 200-250 ° C, it is possible and lower. Then gasoline vapors and unreacted synthesis gas go through the opening (R) from the reactor (6) and through the opening (L) enter the refrigerator (W), where gasoline vapors condense and through the opening (K) they leave the refrigerator. Next, the condensate and unreacted synthesis gas enter through the opening (U) into the condenser (8), where the ready gas accumulates, which leaves the condenser through the opening (P) and the faucet (9) into any container.
The hole (T) in the condenser (8) is used to set the pressure gauge (10), which is necessary to control the pressure in the condenser. It is maintained within 5-10 atmospheres or more mainly with the help of a faucet (11) and partially with a faucet (9). Hole (X) and faucet (11) are needed to exit from the condenser the unreacted synthesis gas, which is recycled back to the mixer (1) through the hole (A). Faucet (9) is adjusted so that clean liquid gasoline comes out continuously without gas. It will be better if the level of gasoline in the condenser increases, than decreases. But the best case when the level of gasoline will be constant (which can be controlled by the built-in glass or some other way). The tap (14) is adjusted so that there is no water in the gasoline / and in the mixer the steam forms better less than more.
Starting the machine
Open access of gas, water (14) is still closed, the burners (12), (13) are working. The tap (4) is fully open, the compressor (5) is on, the tap (9) is closed, the tap (11) is fully open.
Then open the tap (14) of the water, and the tap (11) regulate the desired pressure in the condenser, controlling it with a pressure gauge (10). But in no case do not close the tap (11) completely !!! Then, after about five minutes, the temperature in the reactor (6) is adjusted to 200-250 ° C with a valve (14). Then they slightly open the tap (9), from which the jet of gasoline should go. If it goes on all the time - open the faucet more, if it goes gasoline mixed with gas - open the faucet (14). In general, the more performance you set up the device, the better. You can check the water content in gasoline (methanol) with an alcoholometer. The density of methanol is 793 kg / m3.
This unit is preferably made of stainless steel or iron.
All parts are made of pipes, copper tubes can be used as thin connecting pipes.
In the refrigerator, it is necessary to keep the ratio X: Y = 4, that is, for example, if X + Y = 300 mm, then X must be equal to
Well, perhaps that's all. In conclusion, I would like to add that this design for home-made automotive fuel was published in one of the issues of the Paritet magazine.
The method of producing gasoline from gas and water
Comments of the author-inventor Gennady Nikolaevich Vaks.
Question: What is the consideration regarding the number of compressors needed.
Answer: My installation of 74 code, when gasoline cost something around 40 kopecks and when I had made this machine out of spite, it was designed for high pressure and I needed two compressors.
Now we have perfected it, calculated, it turns out that the process can be carried out by feeding normalized air.
Such a simplification appeared due to the creation of pressure surges in a magnetic reactor.
There inside the environment there are impulses resembling claps.
These claps and their generator are the invention that we brought to the development.
Most of the things that we have described in connection with the methanol installation are well known.
I am not a chemist, I am a physicist and I took data from literature.
The new thing that we have also brought is a very compact heat exchanger.
And the last thing : if in classical reactors for producing methanol (there are many of them, they are common), the particle size distribution of spherical catalyst granules is usually from 1 to
Question: You are recommending three catalysts: copper oxide, zinc oxide and cobalt oxide. With cobalt is very difficult position. Does cobalt increase efficiency slightly?
Answer: I can not say. The chemical composition of the catalyst is taken from classic books. The first plants for the production of methanol worked with a catalyst only from zinc oxide. This is basically zinc white, white powder. But in the future, chemists began to make and on copper oxide and chromium oxide, cobalt oxide. There are a huge number of reports. In GPNTB a whole rack is worth it. These catalysts are more effective than zinc oxide. The proposed method - grinding old " silver " coins, they consist of nickel and copper - gives a good catalyst. They, these sawdust, must, of course, be burned, oxidized.
Question: And you can not add chrome?
Answer: You can not add. Apparently, the optimal catalyst is not yet known. So I think it will just be necessary to try.
Question: The circuit must be tight. But the catalysts will need to be removed and loaded.
Answer: About welding this system. We have recorded that the synthesis reaction takes place at 350 ° C. Therefore, if they had given the fitting scheme and someone had done a little bit wrong, carbon monoxide, hydrogen and methanol vapor, dangerous gases could have leaked into the room. We gave a recommendation - to brew, and this recommendation, in principle, remains. Well, and if someone makes a cork opening with all precautions, naturally with a copper gasket, and not some other one, in order to guarantee the integrity of the process and at the same time disassembly , this is probably possible. And there is no certainty, it is necessary not to be lazy - to brew, then to boil, pour and brew again, with argon.
Question: The journal contains the converter circuit, but nowhere are there any instructions on the technological opening.
Answer: The technological hole is suitable for any, so that you can just fall asleep powder. Regarding the need to compact the powder, I want to emphasize once again the following. In the converter there is both an oxidizer and a reducing agent - methane and oxygen. In the sinuses this mixture is explosive, but if it is in some kind of powder medium, there is no danger. Copper flame-retardant veins are always laid in acetylene tanks in the pipeline, since the flame does not pass back through the capillary. Therefore, we say: it is necessary to fill the converter, shake and fill it again. So that was not the sinuses. In the sinuses may not be big, but the explosion, cotton.
Question: Is the vertical position of the reactor necessary ?
Answer: Vertical is required.
Question: And high-temperature coolers - can be horizontal?
Answer: There are several subtleties that must be observed. Recently, people came: they did - and gas went through their pipes. But they put a collector, well, of the type on the sink, a knee, so that the water could pass, but the gas could not.
Question: You write - it is necessary to warm up before starting. That is the high-temperature heat exchanger ...
Answer: If you noticed, the process is described in several formulas. In the beginning - in the absence of oxygen. The reaction is endothermic, absorption of heat. It will not take place if you do not let the heat down. After you supply oxygen, increasing the pressure - there you have a special screw - the combustion begins to go. In principle, this is not burning, it is an incomplete oxidation. But even then comes with the release of heat. And you no longer need the burner. They are needed only at the beginning of the process.
Question: Ejector: there according to the scheme in the journal the outlet for methane
Answer: There is a small mistake, it is necessary to fix it.
Question: And any mesh should be in front of the ejector against clogging?
Answer: Yes, it is necessary to limit the mesh. I missed it, thanks for the amendment.
Question: Is it possible to make the catalytic pump loading port collapsible? If possible, then what to seal?
Answer: The catalytic pump is the most crucial part. There is better to brew. In principle, the pump should serve a very long time. The main disease of all reactors where a catalyst is used - a catalyst after a while, as the chemists say, is being poisoned. Let's say you have an admixture in your gas - sulfur or something. Some kind of film appears on the surface of the granules. Due to the vibration that we produce, the catalyst is self-cleaning. This is facilitated by the fact that ferrite is more abrasive than zinc oxide - it is very soft. Therefore, the poisoning of the surface is eliminated, and the efficiency of the catalyst is extended.
Question: What is the diameter of the dispersant ?
Question: How is the percentage ratio of methane and water regulated?
Answer: It is regulated by temperature and, in turn, by voltage and degree of vibration. In general, this process is very complex. The system of instrumentation for such processes occupies a solid room. I was at the Tallinn Methanol Plant and saw it. The most complex system. Of course, we could not repeat it. But still implement the process, all this instrumentation, all this feedback, we reduced to one wick. The smaller the flame, the less the unreacted methane, hydrogen, and carbon monoxide are left. The more they do not react, the greater will be a wick of flame at the exit. And you will have to optimize the process yourself. Because gas comes from the network evenly, it is a constant. Before the operator, the main task is to make the wick decrease. For this purpose, both the temperature should be regulated on the disperser , and the air supplied. Day - two spend and learn how to regulate.
Question: The ejector mixer is shown, but the size of the feed tube is not given.
Answer: This diameter does not matter much. It can be 8-10 millimeters.
Question: Is the gas pressure in the trunk sufficient?
Answer: The pressure is what it is, let it be. You still can not increase it, not reduce.
Question: And the air pressure?
Answer: It really does not matter. What we have on the compressor is this pressure sensor, more precisely the pressure regulator. The fact is that this oxygen reaction must have very accurate indicators - from 2 to 4 percent of oxygen in relation to methane. Methane should be 98 - 96%. In fact, we have a compressor with this pressure regulator that plays the role of an oxygen metering unit so that oxygen comes in a strictly metered amount. If you give more oxygen, the process will not work, but there will be a simple burning of methane. The task of the compressor is not to do a lot of pressure. All the same, it moves away from the nozzles, where the ejector, and will be what the gas pressure in the distribution network. The compressor is reliable enough and can operate in continuous mode. If you put the maximum in the refrigerator, the compressor practically works without shutdowns. It has a large margin of safety.
Question: And if they get freon vapors? After all, the compressor is filled with freon oil. J
Answer: If you look carefully, it is made there so that the oil cannot go. You put up the phone and nothing terrible will happen . And if it does, it will roll over the system, that's all.
Question: Is it possible to replace gas burners with electric heating elements ?
Answer: You can.
But it is expensive, probably?
Electricity is more expensive than gas.
Gas can be taken directly from a single burner gas stove.
Flame length approximately 120 -
Question: How to get ferrite powder?
Answer: I can give advice on where to get it. In Belaya Tserkov, near Kiev. There is a factory there. It is necessary not iron, but kerite . Need a pottery. Iron will be oxidized . Armored cores (J) are suitable. They are not hard, they are loose, but not all.
Question: But there is probably an easy way to get small ceramics?
Answer: I do in a normal mortar, grinding through holes in a rag. First, heat the material in a furnace or on gas and then throw it into the water. It will not burst, but will be covered with small cracks, then it can be ground in a mortar.
Question: Heat exchanger brew?
Answer: You can brew. With him, you will not have any problems.
Question: How tough is temperature control?
Answer: Not very hard. Within 100 ° C. You could certainly offer a thermocouple. But most people could not calibrate . Platinum thermocouples are also very expensive. The easiest way is to use thermal paints or even alloys. Each has its own melting point. There should be an alloy of high-melting solder type.
Question: How to start the installation?
Answer: Turn on the burner first. Gas is flowing all over the system. First of all, light the wick. The gas begins to flow through the dispersant and is saturated with water. On the final canister, at the very end, you light the wick, the wick starts to burn strongly. Just burning gas. Nothing else happens. And turn on the entire electrical part. That is, the dispersant is already beginning to work actively, the saturation is active, the burners are burning. The temperature rises to 350 - 800 ° C. Methane conversion begins, which is converted to carbon monoxide and hydrogen. And partly remains untouched methane. Along the way, carbon dioxide appears. Excess water is still coming. The process is endothermic, that is, with the absorption of heat. Gradually, start blowing. This process will last 40-50 minutes. As the heat exchangers heat up, the wick will burn with a variable force. During conversion, heat is released. Then the process will go on itself, it starts to rock itself. I specifically wrote - where is the heat, where - absorption.
Question: What is the expected service life of such an installation?
Answer: The installation will work for a long time, so the lifetime of the catalyst will limit continuous operation.
Here a lot depends on the pollution of the gas, on the properties of the catalyst.
If there is a lot of sulfur in the gas, sulfuric acid may form, it is aggressive at high temperatures.
I apologize for making changes in the parameters of the tubes for the refrigerator.
The first numbers mentioned that they are thick-walled,
Question: Is the use of two heat exchangers justified? Can you do with one?
Answer: That is, do not warm up to the dispersant ? Then you will spend extra heat, extra electricity.
Question: But there will be one heat exchanger.
Answer: In order for evaporation to take place, it is necessary to constantly supply heat. It is necessary that the water was in a certain ratio. Humidity greater than 100%, can not be achieved. But at 100% humidity, the amount of water at different temperatures is different. The higher the temperature, the less moisture at the same moisture percentage (? J). The disperser can create 100% humidity in an air bubble. But in order for this humidity to have a certain amount of water in grams per cubic meter of gas, a certain temperature is also needed. You need to maintain 80-90 ° C and regulate the temperature of the water in the disperser . Depending on this adjustment, you will have a different amount of water per cubic meter of gas. And our formula determines this ratio.
Question: The pressure valve is homemade. And you can KIPovsky , needle?
Answer: You can. It is completely safe here. If the pressure in the system becomes more than the pressure with which the spring presses the ball, then the ball is pressed, and the excess gas is released.
Question: Then what pressure should be?
Answer: And then you look. You, in principle, the compressor of the refrigerator develops pressure up to 2.5 atm. You, apparently, will need 1-2 atm. But you do not need to put a pressure gauge. You only adjust on the wick.
Question: How to insulate the upper chamber of the converter?
Answer: It must be insulated from the outside. There are a lot of different thermal insulation materials, just once we learned to make them from ordinary silicate office glue. It withstands temperatures up to 15000 ° C.
Question: Is it possible to install a converter-reactor close to the installation?
The answer is no.
The distance should be 3-
Question: In the converter reactor, we have height
Answer: Mixing chamber and accumulative chamber should be
Question: Outlet diameter?
Answer: This is your chimney.
Here is 50-
Question: Here it is purely schematically shown - methanol discharge from below. And if in the canister ...
Answer: No, it is impossible.
Question: ... if the straw is down to the bottom ...
Answer: If the tube to the bottom is - possible. It is important not to pour methanol from above.
Question: What is the size of the catalyst particles in the reactor , since the mesh size depends on it?
Answer: 0.05 -
Question: Are we doing the right thing by designing fittings at the outlet and inlet of the reactor, bearing in mind that the connections of the reactor to other units of the installation are made by stainless steel tubes?
Answer: The fittings are shown conditionally. The tubes are welded.
Question: What is the fundamental need for the use of compressors from refrigerators?
Answer: In their durability, reliability, noiselessness, availability.
Question: What pressure should a sealed canister withstand?
Answer: There is no pressure in the canister.
Methanol as a gasoline substitute
Tips and experience from practitioners who install and ride methanol
Gennady Ivanovich Fedan , a mechanic, inventor, he has a lot of his development. His special hobby is the car. By specialty he is a mining engineer, a graduate of the Donetsk Polytechnic University. Working one time as a speedway mechanic , he was introduced to the use of methanol.
Eight years since we started using methanol in the car. During the first two years, we struggled with corrosion. Condensation of water formed, it was necessary to neutralize it somehow. Mostly corrosion struck the piston system. In Zaporozhets, the engine itself is cast iron, and the carburetor is duralumin. The piston system is steel. Corroded valve, valve seats. We tried adding castor oil. It greatly increases compression. Model aircraft, for example, use methanol, adding 15% of castor oil. But there is a lot of corrosion: after each use of this mixture it is necessary to rinse everything.
We were saved from this by adding aviation oil.
I must say that methanol is in many respects very attractive as automobile fuel. Using it significantly reduces the temperature of pressure (?). By the way , our engine is old, rather worn out, and it works fine with methanol. At turns above average, it makes sense to add water. In this case, the fuel supply of the engine increases. I experimentally specify the dosage. I am developing an installation so that there is a metered addition of water depending on the engine operation mode. As soon as high speeds go, the injection starts.
Suppose for some reason you need to temporarily or permanently switch to gasoline. For these cases, I simplified the adjustment of the main fuel system jet. The fact is that under the methanol section must be increased. If you leave the jet as it was for gasoline, then when using methanol will drop power. To avoid this, you need to increase the cross section of the jet, and the engine will work fine.
In winter, the engine with methanol starts much easier than on gasoline, literally within a few seconds.
There is no detonation at all.
Another positive point.
Often it was necessary to assist the owners of "Zhiguli", who had an icy traffic jam in the fuel path.
It is now very often.
Sell gasoline, diluted with water.
On the eye it does not define.
The man bought, poured - and all.
In winter, an ice plug forms in the fuel system.
We have to disassemble the engine, wash it all.
Motorists spend up to two days on this.
Meanwhile, you can literally eliminate the traffic jam within two hours.
Help for " Methanolschikov "
In the August 1991 issue of the newspaper Auto Review, there was an article entitled "The Gasoline Factory ... in the Shed."
It says that a unique gasoline production unit was developed by the Novosibirsk Scientific and Engineering Center “ Zeosit ”.
It can be placed in a freight van and received from
Accidentally in a search engine I stumbled upon your publication and became very interested in its contents. After a brief introduction, inaccuracies made by the author immediately surfaced.
Information about " methanol " was published in the journal "Priority" in N 2.3 for 1991 , and not in the "Parity" as stated in the article, but the completely finished project was published (as far as I know). In these numbers there were drawings of the reactor with electrical control circuit and design of the cooler, after which Mr. Waks (the author of the article) politely apologized and said that further publication is terminated at the request of the power structures of the USSR and those who want to repeat this setting are unlimited.
I would love to get acquainted with this project in more detail (if this is not another soap opera).
I return to the inaccuracies of the article: a catalyst that is recited for the 2nd reactor not GIAL-16, but GIAP-16 (data on the manufacture of catalysts can be found in the book "Technology of Catalysts" edited by IP Mukhlenov et al. 1989. ).
It is strictly forbidden to supply water directly from the tap to the reactor. it contains chlorine , which instantly poison the catalyst at the 2nd reactor, the same applies to gas, which contains impurities of sulfur and active organic substances.
In my installation I used distilled water and monoethanolamine gas cleaning , all this gives a good result.
After a more detailed study of your article, many inaccuracies have surfaced that will be considered a little later.
This information is for those who seek to get the source, i.e. the publication of the journal "Priority", I personally received the data of the journal issue cash on delivery by sending a request to the address of the city of Moscow on B. Communist str., 44, the editorial board of the journal "Priority" tel. editions 272-62-38, 272-27-72 (this was in 1993). I could throw off my magazines , but about 3 years ago they asked me to read the article and did not return it. I only have the 1st issue of the journal , from where the address and tel are taken. edition.
Let us turn to the consideration of inaccuracies of the description of the concept of the apparatus by node.
Stage 1 - as mentioned earlier, water and gas must be cleaned so as not to poison immediately the catalysts 2 and 6 of the reactors.
More precisely, the ratio of pairs : gas as 2: 1 should be adhered to. There should not be a return of unreacted products to level 1.
2nd stage - methane conversion starts at t ~ = 400 * C, but at such t a low percentage of the converted gas , the most optimal t = 700 * C, it is desirable to control it using the chromed alumine thermocouple. The catalyst can be used GIAP-3, it is easier to manufacture .
Refrigerator 4 is recommended for each stage to make your own , this will further facilitate t adjustment and not use a coil for these purposes, it is better to turn to the original source there is a rational grain.
Reactor 6 - it is better to turn to the original source, where the operating principle of the reactor with an electromagnetic pump is described more lucidly and the method for manufacturing an electromagnetic pump is described. Data on the catalyzed can be found in the book of Mukhlenov .
After the reactor, in my installation there is a fridge pressure gauge and a reduction valve set at a pressure of 25–35 atm (the choice of pressure depends on the degree of catalyst wear). I used 2 compressors to inject synthesis gas .
Condenser 8 - I advise you not to make a cylindrical shape , but a conical one (this is done to decrease the evaporation area of methanol) with a window to monitor the level of methanol. The reacted products are supplied from the top of the cone using a tube of 8 mm . The cabin is lowered into a conical vessel below the throttling outlet 9 by 10 mm.
Unreacted synthesis gas is discharged through a tube of 5 mm. which is welded to the top of the cone , the outgoing gas is supplied through a regulating tap to the nozzle where it is burnt. The level of methanol is maintained 2/3 of the total height of the vessel.
This concludes a brief analysis of the article. For those who are going to repeat this installation, I strongly advise you to get acquainted with the literature on this subject, and especially with the book edited by Goykhrakh IM and others. "Chemistry and Technology of Artificial Liquid Fuel" 1954. editions ( star book, but sensible).
