What role does ethanol play in gasoline? What will removing ethanol do to gasoline?

The role of ethanol in gasoline/petrol is that of improving the "research octane number" and thus giving a more efficient burn. Removing the ethanol from the fuel will give rise to the phenomenom of engine knocking and a very inefficent energy transfer ratio.\nzun_noon answer is correct in that there is no ethanol in gasoline/petrol, but it can be used as a fuel additive.  Ethanol is not essentially beer but is found in beer as ethanol is a pure alcohol and you wouldnt want this in your beer.

No, water (H2O) and Gasoline [mostly Octane] (C8H18) are quite different on a molecular level,\nFor one, water has no carbon, and Octane has no Oxygen.

You get napalm.\n\nIf you google "gasoline and styrofoam", the first thing that pops up is a short explanation from totse.com which has a TON of other articles about things like this.

If you remove a molecule of water (H2O) from C2H5OH (ethanol) you are going to end up with C2H4  (Ethene).

sugar cane is recognized as having the least trouble creating ethanol. In Brazil this works wonderfully. They have removed the need to import oil and are actually exporting ethanol. In the US sugar cane doesn't grow as well. sugar cane is best in tropical climates. \n\nIn the US corn is the most common for ethanol. It isn't the best crop but is efficient enough for now. Industry best(meaning in the lab) for producing ethanol is above 1 btu of fuel produces 2 btus of ethanol. \n\nFor non-tropical climates cellulose based ethanol is also making big waves. It's advantages are that every living plant tissue is at least 80% cellulose. Dead tissue like wood is around 30 to 40 percent cellulose. A farmer could sell the normal corn seed, and then bale the corn stalks, which are usually left on the ground, for ethanol. Another advantage is that on irrigated and fertilized lands you can grow better than 10 tons of cellulose per acre per season if grown for harvesting cellulose verus the 2.5 tons per acre of corn seed. critiria for a plant for this process is a plant that grows a lost of mass per acre. \n\nEthanol is meant to replace gasoline fuel not diesel fuel.\nDiesel engines don't have spark plugs, so they can't ignite high octane fuels like gasoline and ethanol. Instead they hammer-strike the better performing low octane deisel fuel. \n\nMost gas engines out there probably can be converted to work with ethanol. There are a number of conversion kits available. It is likely to work better however if they come from the factory. \n\nBio-deisel is wonderful for most diesel engines. I'm afraid I don't know a lot about that topic.

Dry clean them. Gasoline is nonpolar, dry cleaning uses no polar solvents to remove stains and smell that water, a polar solvent, cannot remove.

I don't think all the "experts" are in agreement on the benefits of Ethanol blending.  It burns cleaner, so that helps the environment, but from what I have read, the energy required to produce Ethanol is equal to the energy you create by burning it.  Typically we burn fossil fuels in the Ethanol creation process, so other than propping up the corn industry, we haven't gained a thing.  So in answer to your question, are Toyota and Honda doing anything with Ethanol, unless they can cheaply modify their cars to burn gas and/or ethanol, I doubt if they'll do anything with it. If we pass laws to forcibly raise the amount of Ethanol consumption in the US, that might force the Japanese car manufacturers to accommodate Ethanol.

if clean and free from water, mix it with fresh gas and use it in your car or lawnmower. it thickens a bit and breaks down with age but is still usable diluted.\n\nYou can get a fuel stabilizer at most car parts stores to add to gas before storage, it'll extend the storage life of the gas substantially.

The engines are designed to run on gasoline which burns a little differently and much dirtier than ethanol. ETOH burns to only CO2 and H2O, very clean. Ethanol can be made easily from any organic material. Corn stalks, wood, petroleum, potatoes, sugar, whatever you have mostly. Crack the large molecles to 2 carbons with an OH attachesd and you have ethanol. Fermentations with yeast are usually the easiest way.

Most would settle to the bottom of the tank and join all the rust that's already there. Carbon and Potassium Nitrate aren't soluble enough in gasoline (and neither is the graphite form of carbon used to polish the granules in commercial gunpower).\n\nHowever, the sulfur would partially dissolve and eventually ruin the car's catalytic converter. It might even lead to a bit of a smelly exhaust for a while.\n\nNow, if you didn't mean gunpowder, but mean nitrocellulose (which is a more common propellant in modern guns), then you could give him a nice octane boost. However, it takes several days to a week for nitrocellulose to dissolve in gasoline (depending on temperature and 'shaking'). So, don't expect much very soon.\n\nI think the thing you are missing here is that gasoline isn't burned in the tank. Only a small, filtered amount is burned in the engine at one time. That's why you get miles per gallon and not gallons per mile.

Market it to intellectuals. Some student at my school (chemists, I think) proposed that we use the excess grease from the dining halls to be converted to ethanol on campus in a lab they built and now all of the facilities vehicles are running partially on ethanol (I think it's a mix of ethanol and gasoline, but I could be wrong). \n\nThe layperson isn't going to be interested in ethanol until it becomes mainstream. The best bet is to start getting Universities and Hosiptals to run their vehicles (ambulances, security vehicles, construction vehicles). \n\nAlso, it would be sweet if the government supported ethanol usage by providing tax incentives for these companies (like you get if you buy a hybrid car). It's really very frustrating because ethanol production is so inexpensive. I feel your pain.

Since sugar is NOT SOLUBLE in gasoline, it won't actually do anything but clog up your fuel filter, possibly damage your fuel pump, and might clog your injectors if it gets that far. \n\nHere is the research that supports this:\n(I quote Snopes.com)\n"Sugar doesn't dissolve in gasoline, as a researcher at Berkeley confirmed in 1994. Forensics professor John Thornton labeled sucrose with radioactive carbon atoms and mixed it with gasoline, then spun the concoction in a centrifuge. After the undissolved particles were removed, the liquid's radiation level was measured to determine how much sucrose had become part of the gasoline. The answer was extremely little: the equivalent of less than a teaspoonful per 15-gallon tank of gas.\n\nBecause sugar doesn't dissolve in automotive fuel, it doesn't carmelize, and so it does not turn into the debilitating gunk..."\n\nI have had my gas tank sugared, and the only problem it caused me was that the truck wouldn't start.  I had to clean the sugar out of my carburetor (it was an old truck) and drain my gas tank. Two hours of messing around and I was back on the road. Sugar is not even very effective for damaging cars, much less improving mileage.\n\nIf you want to improve your gas mileage:\n1. inflate your tires properly (this can add 10-20% to your mileage)\n2. Accelerate slowly- don't be a leadfoot\n3. Stay under the speed limit and drive under 55 mph where possible. If you have a standard transmission try to drive in the highest gear possible at the lowest RPM that your engine operates at effectively. \n4. Ride a bicycle for local trips.  \n\nAnd I suspect your friend is trying to have a laugh at your expense.

Well, ethanol is a hydrocarbon, so the combustion reaction is:\n\n2C2H5OH + 7O2 --> 4CO2 + 6H2O\n\nThis reaction produces a lot of energy. If an engine is created for ethanol use, it can utilize that energy in a cylinder just like a normal engine.

The most recent spike in prices is due to the elimination of MTBE as an oxidiant in gasoline. The rules protecting the seller from lawsuite over MTBE change on May 5. There is a serious concern there might not be sufficient ethanol to make up for the MTBE loss.

Ethanol relaxes the DNA, making it leave its partner, much like the effect it has on humans...\n\nJust kidding
