摘要：In the present work, pretreatment of sweet sorghum stalk using dilute acid was investigated under mild conditions. Process parameters investigated include reactor temperature, reaction time, and acid concentration. Xylose concentration, xylose yield, and decomposition product concentrations are measured. The highest yield of xylose (77.5%) is achieved under optimum conditions. The optimal conditions selected are 0.75% (w/w) acid concentration, 140 degrees C, and 10 min Using theses conditions, 23.9 g/L of xylose concentration, 0.98 g/L of furfural, and 2.52 g/L of acetic acid are obtained. The decomposition product concentrations are low.
