Fuel grade ethanol can be made by biological or chemical routes.
- For biologically based ethanol starches or sugars from plants are fermented under anaerobic conditions and the produced ethanol is distilled to the desirable level of purity.
- For the chemical process, light gases from petroleum is reacted to create ethane or ethylene and an OH- is substituted for one of the hydrogen's in the alkane or inserted into the double bond to make ethanol.

Why is hydrogen a cleaner fuel than ethanol?
Hydrogen is a cleaner fuel than ethanol because, unlike ethanol, it does not contain hydrocarbons (which when burnt release harmful carbon dioxide and monoxide gases.). Hydrogen only produces water as a byproduct when used in combustion, so it is a cleaner fuel.
How can ethanol be used?
Ethanol has two main uses. People drink it to become intoxicated (mildly or severely), and it can be added to gasoline to make a fuel called gasohol. It can also be used as rubbing alcohol although isopropyl alcohol is preferred if only because it is not drinkable.
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.
How is ethanol used as a fuel?
It's a combustible liquid, so it can be used pretty much the same way as gasoline is used.
What is the fuel made from sugar cane?
Ethanol fuel
Why is ethanol used in fuel for cars?
No
What is the fuel used in Indianapolis 500?
Ethanol is the fuel used in the Indianapolis 500.
Can ethanol be used for car fuel?
yes
What does ethanol and calcium acetate make?
Solid fuel
What is used as fuel in place of the methylated spirits?
ethanol
What are some new things that are being done with corn?
They are making ethanol fuel from it. It is also being used to make plastics.
How to make fuel?
Ethanol fuel can be made by combining food supplies and a few pieces of equipment.
What does the ethanol blend e85 consist of?
E85 is an ethanol blend of 85% ethanol and 15% gasoline. It is primarily used as fuel for flex-fuel vehicles, which are designed to run on a range of ethanol-gasoline blends. E85 is considered a renewable fuel source and offers certain environmental benefits, but its use may result in reduced fuel efficiency compared to gasoline.
Why alcohol cant be used as a fuel in diesel engne?
While diesel engines do use fuel with the highest percentage of ethanol (Grain alcohol), they do not use 100% ethanol.
How can agriculture be alternative to oil?
The key word in the answer is ETHANOL. Ethanol comes from corn. Therefore agriculture...grow corn, make fuel from the corn, power cars from Ethanol
How much of a bushel of corn is used to make ethanol?
Assuming the dry-milling method of ethanol production (the most common), one 56-pound bushel of corn makes 2.7 gallons of fuel ethanol and 17.4 pounds of dried distillers' grain. This means that 69% of the corn went into the ethanol.
Can alchol fuel cars?
In theory yes but there's very little point in it as you can either get ethanol from crude oil through distilling and cracking through which you can also get diesel and petrol from. You can also make ethanol out of vegetables but again you can also make diesel. The main use of ethanol in running cars I would say is bio-petrol which is just a mixture of petrol and ethanol. All this achieves is less petrol being used. But yes, you can fuel your car on it after modifications but it's more commonly used as an additive to petrol.
