ethanol produced from waste material?
966310
Ethanol is an alcohol made from renewable  resources such as corn and other cereal grains, food and other beverage wastes  and forestry by-products. Ethanol-blended fuel substantially reduces carbon  monoxide and volatile organic compound emissions, which are precursors to  ozone.Â  The corn-based substance is added to gasoline blends to meet oxygenate  level requirements mandated by the 1990 Clean Air Act Amendments and to raise the octane level.

Make a small scale ethanol still.  Lots of instructions on the net.  Kind of a hot topic with all the discussion of alternative fuels.

I live in Nebraska & of the several ethanol plants already in production, 13 more are going to be built in the next 2 years. Ethanol will begin using more corn than feed for animals.\n\nThe price keeps going up because of Federal guidelines regarding cleaner automotive gas.  MTBE was outlawed a few years ago & states must use cleaner alternatives in fuel or they lose their federal highway funding. It's known as Methyl Tertiary Butyl Ether if I remember correctly and when it leaks from tanks one drop can contaminate 10,000 gallons of water and it's nearly impossible to clean up (my bro's a chemist).\n\nThe demand continually goes up for these alternative fuel additives which drives up the price.\n\nI can tell you that as of the last 3 months we haven't even had fuel at gas stations WITH ethanol. Ethanol gas here was usually 3 cents cheaper, but now it's all being exported, so we're building more plants to meet demand.

the production of alcohol is an anoxic reaction, if oxygen is present alcohol isn't produced. This is usually achieved by putting the fermentation mixture in a sealed flask with a water stopper in the top, this allows the escape of CO2 produced in the fermentation but doesn't allow O2 in the air to dissolve in the water

The gas shortage was because they had to completly empty out the underground storage tanks (USTs) to completly remove any water that might be in there before putting the 10% ethanol fuel in there! \nEthanol is a cleaner burning fuel and hopefully will be our new gasoline soon. Ethanol can run in all vehicles and once they figure out how to make ethanol more economically, then I believe it will be a main fuel for the U.S.A.

Ethanol has a low flash point (-5 C), which is the temperature at which enough vapors in the air can be present to create an explosive atmosphere; a spark or flame can cause an explosion.  It also does burn with a weakly colored flame, making it hard to see.  \nAlso - high-strength ethanol that you can by is called denatured alcohol - there are many kinds, but they are all poisoned with something - methanol, isopropanol, toluene etc. which render it undrinkable.  Don't do it.\nPunch in "MSDS" and "ethanol" into yahoo and pull up a material safety data sheet.

Ethanol is bad and creates many nasty acids that wear away the journal bearing babbits, etc.  Many materials cannot stand up to the increase acidity present when burning higher percentages of ethanol. (Boy i hope i don't mean methanol instead of ethanol.  You might want to double check me there!)\n\nCNG can ONLY be used on SUPERCHARGED diesel engines.  To date, there are no SUPERCHARGED automotive diesel engines made.  The only way to get CNG into a diesel engine is to use very large superchargers which run mechanically off the crankshaft to ensure enough air-fuel mixture gets into the engine.  See Waukesha for stationary CNG products.  Traditionally, many diesel/CNG power plants run on CNG most of the time to save $.  \n\nCNG is GREAT for normally aspirated automotive spark-ignition engines.  It may produce less peak power, but the cylinder wear is REDUCED, oil contamination REDUCED--the engine runs SO MUCH CLEANER it is unbelievable.  Combustion chambers remain spotless and spark plugs stay clean.  CNG evaporators need a heat source, so in cold climates you may have to have a preheater.\n\nYou may be able to increase compression ratio when building up an automotive conversion--but don't overdo it.  I know plenty of CNG trucks that end up blowing a head gasket because people have a lead foot.  You could probably run a 9.0.  The best engines to use are V-8 carbureted truck engines.  \n\nTotal fleets of frozen food delivery trucks have been converted to CNG--but none has a diesel engine--they are all gasoline type engines.  So they do use them in trucks.  \n\nCNG will run out fast in your automotive application.  CNG must be stored in a gas phase, which means by the cubic foot.  It is not practical usually to build CNG storage into a car, and check with your Dept. of Transportation on explosion hazards--it may be illegal in some cases to carry so much cubic feet of explosive gas on a car or in a non-rated tank.  The heating value, i.e. energy per cubic foot of fuel is far less than gasoline, and less than propane. \n\nThe most practical conversions for cars are propane kits.  They are very simple: pressure regulator, evaporator, and some kind of throttle linkage.  You will get a few more miles per bottle of propane than CNG.  Both propane and CNG keep engines spotlessly clean.  Be sure to start with a clean engine and be sure that the valves have valve seats in the heads.  Exhaust gases can run the valves a bit hotter than when burning gasoline because of unburnt hydrocarbons in the exhaust--if your air-fuel ratio is right, you will never have that problem with CNG or LPG.

You'd need 4 L of dehydrated alcohol and 1 L of water in order to get a 80% solution. Getting a dry solution of ethanol would be a challenge, though, so I would expect it to be closer to 75-77% in actuality (but theoretically 80)

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.

sugars + yeast + water = ethanol ;I wouldn't drink it though unless you know what you are doing. There is always the possibility of methanol contamination that's the reason for distillation. IF YOU DRINK IT YOU COULD GO BLIND!!!

ethanol is not cost effective. It takes more energy to produce a gallon of ethanol than can be created from it.  The only thing supporting it is the government giveaways--your tax dollars.  Another subsidy for the campaign contributors.  If it were not for stupid greedy politicians there would be none.

one is propanol..the other that u can derive is 2-methyl ethanol...i thinks that's the iupac name..not sure about the commercial name

The best plant for ethanol are sugar producing plants such as sugar cane. However sugar cane doesn't produce enough volume. In the US there are only a handful of states that can grow it. \n\nThe best volume types are cellulose. That is the material that surrounds a plant cell. Except for wood, all plants are extremely high in cellulose. \n\nThe problem is breaking cellulose into sugar. The best known way to treat it with heat and chemicals. Scientists are working on bacteria that will consume cellulose and output sugar as waste. Another dozen years this will be ready to implement. \n\nThe current technology on this is far more efficient than corn to ethanol converstion a dozen years ago. Today, even without the special bateria, cellulose ethanol is very good.

You would want to look for ethanol producers.  They ship the ethanol to refiners who mix it with gasoline to make E85.  Most ethanol producers are farmers or co-ops that aren't publicly traded.  For right now, your best bet at investing in an ethanol producer is PACIFIC ETHANOL INC (PEIX).
