2.2 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 C6H1206 2C2H5OH + 2002 When the solution reaches 12% ethanol, the yeast dies and the reaction stops. (a) How many bushels of com are required to produce 500 tons of pure ethanol per day? Assume 1 bushel of corn weighs 56 lb. (b) The process requires 72 hours to go to completion. What size batch-reactor tank or tanks are required for this process
