木质纤维物料的爆炸冲击裂解预处理新方法

研究了一种新的天然木质纤维原料膨化裂解爆炸冲击预处理技术。结果表明,玉米芯等天然木质纤维试样处理后,纤维束长度变短、排列呈无序化,纤维生物组织形态和结构发生明显变化,呈膨化疏松状态;稀酸水解定量测定结果表明,处理后试样的总还原精得率获得大幅度提高。玉米芯试样的纤维素水解率达80％以上,水解率和水解速率成倍提高。

A new method for pretreatment of ligncellulosic materials by explosive shock

A new explosive shock dilatation and seperation technique for pretreatment of natural lignocellulosic materials was studied.The results shows that treatd natural lignocellulosic sample such as com cob etc,their length of fibre bundle shortens,fibre bundle arrange disorders,biomass appearance and structure of samples largelyu change to be dilataion and loose state.The dilute acidhydrolysis quantitative measure results shows that overall yield of the reducing sugar of treated samples largely increase,hydrolysis rate of com cob sample is over the 80%,the rate and speed of hydrolysis are increased by times.
