A 50 milliоn gаllоn аnnuаl capacity ethanоl plant is being planned. Ethanol is to be produced from locally grown switchgrass using a lignocellulosic fermentation technology (biochemical platform). Switchgrass is harvested once annually, contains 30% moisture and crop yield (includes moisture at harvest) is 14,000 kg/hectare. Average organic composition of switchgrass on dry basis is as follows: Cellulose (C6H10O5) = 50%; Hemicellulose (CH1.6O0.8) = 10%; Lignin= 15%; Ash= 8%; Extractives= 17%. Write balanced stoichiometries for the microbial conversion of cellulose and hemicellulose to ethanol. Using the above stoichiometries, calculate the ethanol yield from cellulose and hemicellulose in g/g. What is the yield of ethanol from switchgrass as harvested? Express this yield in L per metric tonne. How much switchgrass as harvested is required annually as feedstock for the plant? Assume 100% conversion of sugars and no losses during processing. Calculate the land area in hectares required to grow switchgrass that will meet the demand of the ethanol facility.
