| 摘 要： | 目的]优化稻草秸秆浓硫酸水解法的条件。方法]在单因素试验的基础上,固定稻草秸秆粒度为20~40目,以液固比（V/W）、硫酸质量分数、反应温度和反应时间4个因素进行正交试验。结果]4个因素对稻草秸秆水解率的影响程度为：硫酸质量分数〉液固比〉反应温度〉反应时间。稻草秸秆的最佳水解条件为：硫酸质量分数70%,液固比（V/W）12∶1,反应温度70℃,反应时间为3 h。在此条件下,稻草秸秆水解率达77%以上。结论]该研究为综合开发利用稻草秸秆奠定了基础。

| Abstract: | Objective] The research aimed to optimize the concentrated sulfuric acid hydrolysis conditions of rice straw.Method] Based on the single factor test,the liquid-solid ratio(V/W),the mass fraction of sulfuric acid,the reaction temperature and the reaction time were selected to do the orthogonal experiment when the particle size of rice straw was during 20-40 screen mesh.Result] The effect degree of four factors on the hydrolytic ratio was the mass fraction of sulfuric acid >liquid-solid ratio> reaction tim... |
