In ethanol production by fermentation of corn, hydrolyzed ground corn in a water suspension containing 50% corn by weight is mixed with sufficient enzyme to produce ethanol by the approximate reaction 3.6 c& h12o6 2c2h5oh+ 2co2 when the solution reaches 12 wt% ethanol, the yeast dies and the reaction stops. how many bushels of corn are required to produce 500 tons of pure ethanol (a) per day? (1 bushel = 25 kg, 1 ton-907 kg as opposed to 1 tonne 1000 kg) the process requires 72 hours to go to completion. what size batch-reactor (b) tank or tanks are required for this process? assume density of starch 1000 kg/m3.
