A typical biomass pretreatment to ethanol production is represented by the attached figure. In this example, switchgrass is used for ethanol production. The composition of the switchgrass is 37% cellulose, 24% xylan, 3% galactan, 4% arabinan, 20% lignin, 7% extractives, and 5% ash. A dilute acid pretreatment method is applied to the switchgrass before enzymatic hydrolysis and fermentation. The pretreatment hydrolyzes 10% hexosan and 90% pentosan into monomeric sugars. Approximately 30% of the hydrolyzed pentoses are decomposed to furfural. Assume that there is no decomposition of the hydrolyzed hexoses. How much (in kg) of glucose is produced when pretreating 1,000kg (dry matter) switchgrass?
