The corn mash is transferred to fermentation tanks and is mixed with yeast and allowed to ferment for 40 to 50 hours, which changes the sugar to ethyl alcohol and carbon dioxide.

Can gasoline engines run on 100% ethanol?

Pure ethanol – 100% ethanol or E100 – could theoretically be used to power cars, but generally isn't, for numerous reasons: Ethanol is bad for cold-starting, because it doesn't burn as quickly as gasoline. (It has a higher octane, if you're interested.) Pure ethanol would be useless as fuel in the winter months.

What crop might be better than corn for making ethanol?

New research from the University of Illinois shows producing ethanol from grasses rather than corn could significantly cut greenhouse gas emissions in the U.S. without affecting food production. The grasses -- Miscanthus and switchgrass -- grow year-after-year without replanting and require less fertilizer than corn.

Can a car run on pure ethanol?

However, most cars don't run on pure ethanol – in fact, running on higher than 15-20% ethanol concentration can cause engine damage because the engine has to be adjusted to account for the differing combustion property of that concentration.
