摘要:
分别以稻草秸秆、经预处理的稻草秸秆、脱脂棉、微晶纤维素和定性滤纸为原材料,利用间歇式的超临界反应设备,在400℃的盐浴中进行木质纤维素的超临界水解,采用3,5-二硝基水杨酸(DNS)法对产物中的还原糖进行测定,研究反应时间对不同纤维素原料水解产糖的影响。结果表明:在超临界条件下,不同原料在较短的时间内还原糖含量均出现峰值,随着反应时间的延长还原糖产量呈现下降的趋势;稻秆、预处理后的稻秆、脱脂棉、微晶纤维素和定性滤纸的最大产糖量分别为7.42、9.05、12.55、18.01和14.24 g/L;与此对应的最佳反应时间分别为3.5、4、3、3、4 min;对应的最大还原糖产率分别为14.84%、18.10%、25.10%、36.02%、28.48%。
