| 摘要: |
| 用硫酸作催化剂水解蔗髓木质纤维素,考察不同催化剂用量、水解液固比、水解时间以及温度对蔗髓水解生成木糖、葡萄糖、阿拉伯糖和糠醛的影响。结果确定出蔗髓稀酸水解处理的最佳水解条件是:催化剂用量130%、液固比20、水解温度120℃,时间20min,在此条件下,木糖产率23.06%,葡萄糖产率1.97%,阿拉伯糖产率0.85%,糠醛产率2.34%。 |

| Abstract: |
| Experimental trials of sulfuric acid catalyzed bagasse pith hemicellulose hydrolysis were conducted.Different hydrolysis conditions were tested and the best hydrolysis conditions were developed as:130% catalyst loading, the ratio of solid to liquid was 20, the temperature was 120℃ and the hydrolysis time was 20min.With these conditions, 23.06% yield of xylose, 1.97% yield of glucose, 0.85% yield of arabionose and 2.34% yield of furfural were achieved respectively. |
