- 摘要:
- 为优化一种较适宜稻草秸秆糖化降解的方法,对4种化学试剂催化水解稻草秸秆进行了研究。对质量分数、糖化温度、糖化时间、液固比4个因素进行单因素试验分析,选取糖化效果最好的试剂进行正交试验。结果表明:盐酸糖化的效果最好,酸固比30∶1,糖化温度为60℃,质量分数为22%,糖化时间35 h,在此条件下,还原糖含量为30.45%。
- Abstract:
- In order to optimize a saccharification degradation method,hydrolysis of rice straw catalyzed by four kinds of chemical reagents were studied,dosage of catalyst,temperature and time of scarification,liquid-solid ratio had been analyzed in single factor experiment.And the reagent with best catalytic effect was selected and analyzed in orthogonal experiment of rice straw scarification.The resultd showed that the saccharification of hydrochloric acid was the best.With solid-liquid ratio of 30∶1,22% sulfuric acid,the reducing sugar content was 30.45% in hydrolysate after 35 h scarification under 60℃.
