| 摘 要： | 为有效提高木质纤维原料的综合利用率,笔者提出了用酸性亚硫酸氢钠预处理分离半纤维素和纤维素的工艺。以竹浆产业加工剩余物为原料,进行了原料预处理、戊糖脱水环化和木素脱除的一系列实验。实验结果表明:亚硫酸氢钠预处理可以实现聚戊糖大部分水解,水解率达到90.78%;在非最优条件下,采用Milox溶剂法进行水解底物木素脱除,木素脱除率达到98.91%。

| Abstract: | In order to make the utmost of lignocellulosic materials, this study proposted separation process of hemicellulose and cellulose by sodium bisulfate hydrolysis. Experiments which include pre- hydrolysis, dehydration cyclization and delignification were done with processing surplus of bamboo pulp industry as raw material. The results showed that most pentosan were hydrolyzed by sodium bisulfate hydrolysis, hydrolyze rate was 90. 78%; lignin removal rate was 98.91 %with method of Milox. |
