Abstract

Pretreatment is an indispensable procedure for the effective utilization of wheat straw.In this paper,the effects of the physical the chemical treatment including acid-alkali treatment,freezing treatment and high-temperature high-pressure treatment etc.on wheat straw were investigated.The results showed that after 60 min steaming cooking of wheat straw in dilute sulfuric acid at 121 ℃,the content of reducing sugar in the solution increased evidently and the degradation rate of wheat straw could reach 20.6 %.
