Amount of ethanol that can be produced from corn grain is capped at 15 billion gallons. The starch portion of the grain is converted to ethanol. The stoichiometry for conversion of starch (C6H10O5) to ethanol (C2H5OH) can be written as follows: C6H10O5 + H2O → 2C2H5OH + 2CO2 A. Using the chemical composition data of corn grain from Table 4.2 of the exam handout, estimate the ethanol yield (in Liters) from a metric ton of corn grain as harvested. The moisture content of the grain at harvest is 20% by weight. B. Currently corn is harvested from 35 million hectares in the United States, this includes corn for food, feed and fuel ethanol. It is proposed to use 70% (by mass) of the residue produced from corn harvest for making ethanol by biochemical conversion. This residue is termed corn stover and refers to stalks, leaves, cobs and tassels left in the fields after harvesting the grain with a combine (Table 4.10, exam handout). The rest of the residue is tilled back to soil to retain soil organic carbon. The moisture content of corn stover is 35%. Biochemical conversion methods only transform the cellulose and hemicellulose of the corn stover to ethanol. Table 4.3 of exam handout lists the composition of corn stover. Calculate how much ethanol can be produced from corn stover annually. The stoichiometry for conversion of cellulose (C6H10O5) and hemicellulose to ethanol is as follows: Cellulose: C6H10O5 + H2O → 2C2H5OH + 2CO2 Hemicellulose: CH1.6O0.8 + 0.2H2O → 0.33 C2H5OH + 0.33CO2 C. If corn stover is also used to produce ethanol as described in part (b), what is the total annual ethanol potential (in gallons) from corn (grains and stover) in the USA?
