Is Ethanol Made from Corn Stover a Sustainable Transportation Fuel?Sheehan, JohnAden, AndyPaustian, KeithKillian, KendrickBrenner, JohnWalsh, MarieNelson, Richard
While methanol has one carbon atom, ethanol, the next largest and derived from the pure hydrocarbon ethane, has two. The chemical formula for ethane is CH3CH3(also written C2H6); each carbon atom is bound to three hydrogens and to the other carbon atoms. The formula for ethanol is therefor...
