  • A Statistical Analysis of the Theoretical Yield of Ethanol .

    of the theoretical yield of ethanol from absolutely dry corn grain is somewhat lower than the 0.374 kg EtOH/kg dry corn in (Patzek, 2004). According to Remark 1, the theoretical ethanol yield in dry grind plants may be higher. The U.S. ethanol industry uses a confusing and imprecise system of units and it customarily exagger-ates ethanol yields.
