Corn for Biofuel Production

Corn (Zea Mays) is a popular feedstock for ethanol production in the United States due to its abundance and relative ease of conversion to ethyl alcohol (ethanol). Corn and other high-starch grains have been converted into ethanol for thousands of years, yet only in the past century has its use as fuel greatly expanded. Conversion includes grinding, cooking with enzymes, fermentation with yeast and distillation to remove water. For fuel ethanol, two more steps are included: molecular sieve to remove the last of the water and denaturing to make the ethanol undrinkable.
