what is the process of producing ethanol from rice grain?

Answer 1

Fermentation of the rice in water. (boil the rice and add yeast to the cooled, strained liquid) After the "beer" has maxed out on its production, you boil the finished beer and force the super heated vapor some sort of condenser. (moonshiners sometimes used car radiators which would be OK ONLY for fuel, as there is lead in radiators, and your "fuel" would be toxic). The condensed liquid returns to the boiler and the mess continues. Keep adding more beer and after running your still quite a while you will have a vodka like material. (40% alcohol) and if you keep boiling off the water long enough and catching the alcohol you will end up at 80 or 90%. Beyond that I think you need other equipment to actually make pure Ethanol. Just remember it's illegal to distill alcohol, and you can buy a bottle of Everclear fairly cheaply. The Foxfire series had a great article on making corn whiskey which is pretty much the same process, and they go into detail on the equipment, check it out.

Answer 2

Ethanol, also suggested as ethyl alcohol, grain alcohol, or eating alcohol, is optimum elementary because the style of alcohol recent in alcoholic drinks. In elementary utilization, that is often suggested only as alcohol. Sugars for ethanol fermentation must be received from cellulose. till presently, although, the fee of the cellulase enzymes able to hydrolyzing cellulose has been prohibitive. Its wide-spread customer so a techniques has been the authorities, which, has invested heavily interior the commercialization of cellulosic ethanol. Deployment of this technologies ought to turn distinct cellulose-containing agricultural with techniques from-products, which include corncobs, straw, and sawdust, into renewable power factors.
