摘　　要：对利用树脂型固体酸催化剂催化水解稻草秸秆制备可溶性糖工艺进行了研究,单因素考察了固固比、固液比、反应温度、反应时间、秸秆目数对秸秆水解产率的影响。研究结果表明:秸秆粉碎至100目,常压下固液比(反应体系中固形物与液体质量比)为1∶10、固固比(树脂型固体酸与秸秆质量比)为1∶1、反应温度100℃、反应时间15 h为最适反应条件,在该条件下树脂型固体酸催化水解稻草秸秆反应的水解产率为32.5%。该新工艺为稻草秸秆的水解利用开辟了一条绿色环保的新途径。Solid acid catalyst is used to hydrolyze rice straw in different reaction conditions in order to get soluble sugar. By single factor experiment, the effects of solid-solid ratio, solid-liquid ratio, reaction temperature, reaction time on the hydrolytie reaction of rice straw are investigated. The results show that the optimal reaction conditions are as follows ： 1 ： 10 of the solid-liquid ratio, 1 ： 1 of the solid-solid ratio, 100℃ of reaction temperature, 15 hours of reaction time. Under the optimal conditions, the yield of catalytic hydrolysis is 32. 5%. This new teehnology opens up a new environmentfriendly way for the hydrolysis of rice straw.
