Ethanol has many considerations as far as its use as an automotive fuel.\:
# On the plus side it is a liquid and easily handled in the present transportation and delivery systems. # On the negative side: * Ethanol from food crops removes food from the system * It requires more energy to produce ethanol than the automobile gets out of the ethanol (Crops require fertilization and fertilizers are made using hydrocarbons, ethanol is made by fermaentation, the fermentation products require distillation, the ethanol is a less efficient fuel than gasoline) * Ethanol combustion creates tail pipe emissions of aldehydes and ketones at levels not present in hydrocarbon fuelled autos * There is not enough land to produce enough ethanol fuel while maintaining food production * Ethanol from waste cellulose is not being pursued asa production route

Which country produces ethanol?
US, and then Brazil produces the most ethanol fuel...nd I'm sure every countries that has ethanol industry would produce ethanol fuel!
Does esso premium unleaded gasoline contain ethanol?
does esso premium fuel have ethanol
What is a better fuel propanol or ethanol?
probably ethanol - it is more readily available and vehicles are set up to take it
How is biomass converted into ethinol?
Ethanol (ethyl alcohol), also known as grain alcohol, is the same 'alcohol' found in all alcoholic drinks. Bioethanol is simply ethanol that has been produced using biological materials (biomass) for feedstocks. Since it relies on sunlight and photosynthesis to contribute to the growth of that biomass (plants, grasses, corn, wheat, etc), bioethanol is a renewable fuel. Bioethanol is made when biomass is converted to sugars, which are then fermented into ethanol. The process of hydrolysis seperates most of the water from ethanol, leaving an end product that is generally about 95% ethanol and 5% water. Bioethanol can be blended with conventional gasoline at any ratio, but the most common blend is E10 (10% ethanol, 90% gasoline, sometimes called Gasohol), which can be used in existing gasoline engines without modifications and without affecting vehicle warranty. Higher blends, such as E85, require a Flexible fuel vehicle (FFV).source: http://www.futurecars.com/futurefuels/bioethanol.html
What is the best thickener for fuel gel with ethanol?
Lubrizol's Carbopol EZ-3
Which countries lead in the use of ethanol fuel?
Brazil is the leader using as high as 25% Ethanol+Gasoline mixture... very closely followed by USA.. other countries like China, Australia, Sweden, Colombia use Ethanol as fuel.
How much Ethanol is in the fuel NASCAR uses or if any?
I don't believe that NASCAR is using ethanol. I know F1 race cars use it.
What is Brazil a pioneer and world leader in?
using ethanol made from sugar cane as a fuel
Can you give me a sentence using the word ethanol?
Ethonal is a type of fuel made from corn.
How can ethanol reduce carbon emissions?
Ethanol is a fuel made from plants. When we burn this fuel, it does emit carbon dioxide, but of course this was originally absorbed from the atmosphere by the plants, so there is no net increase in the amount of atmospheric carbon dioxide no matter how much ethanol we use (apart from a small amount produced by generating electricity used in the production of the ethanol). A disadvantage of using ethanol for motor fuel is that its production competes with food crops.
Can you use boat fuel in a car?
If we're talking about gasoline/petrol, then yes as long as it meets the minimum octane required for your car. If you consider "boat fuel" as ethanol free fuel then yes absolutely you can. Using fuel containing ethanol in boats however creates problems.
Which country produces ethanol?
US, and then Brazil produces the most ethanol fuel...nd I'm sure every countries that has ethanol industry would produce ethanol fuel!
What is aviation turbine fuel?
it is a fuel of geometeriological ethanol
What is the fuel made from sugar cane?
Ethanol fuel
What kind of fuel additive should you use for a 1992 Chevrolet work truck when using gasoline with ethanol?
Unless this is a Flex Fuel vehicle you should not use E85 and should use only gasoline with 10% or less Ethanol. There is no additive to help.
Why ethanol may be considered a better fuel than gasoline?
IMO, it is not a better fuel. Ethanol has nothing going for it. It contains less energy per gallon than gasoline. You get less milage and less power, with ethanol. It is no cheaper to produce as it must be trucked and cannot be piped. It takes away from the food supply to produce fuel. The rain forest is being cut down in order to grow crops for the production of ethanol. Ethanol is just a way to stop using oil, and a poor way at that.
Which entrainers can be used in ethanol water separation to obtain fuel grade ethanol?
Benzene or cyclohexane can be used in ethanol-water separation in order to allow distillation of ethanol past the azeotrope point (96.5% ethanol by volume). Of course the benzene (a known carcinogen) must be separated from the water before the water can be disposed. Fuel grade ethanol is often separated from water using molecular sieves. In this kind of separation water is entrained in "beads" which absorb water but reject ethanol. These are eventually regenerated for reuse.
