Abstract:
Taking Pennisetum sp.as material,the effect of solid-liquid ratio,acid concentration,processing time and processing temperature of H2SO4 on chemical composition of Pennisetum sp.and the reducing sugar content in enzymatic hydrolysis solution were studied.The results showed that the best dilute acid (H2SO4) pretreatment methods were as follows:solid-liquid ratio 1∶20,acid concentration 2.0%,treatment time 60 min and processing temperature 100℃.This article conducted a preliminary exploration for giant Juncao as bio-ethanol fuel.
