Abstract

Abstract:

The saccharification of crop straw by hydrolysis was carried out under the condition of microwave radiation with the dilute sulfuric acid. The amount of sulfuric acid, the ratio of liquid and solid, the microwave radiation time, the pressure, and the power on the yield of reducing sugar were investigated. The experimental results show that the yield of reducing sugar increased at first and then declined with increasing of the experimental conditions．It was determined that the yield of reducing sugar reached the maximum, 21.8% at the following conditions: the amount of sulfuric acid is 2%, the ratio of liquid and solid is 15.0, processing time is 40 min, the pressure is 0.3 MPa, and power is 225.0 W.

摘要： 在微波辐射条件下,对玉米秸杆进行酸水解糖化实验,考察了硫酸质量分数、液固比、微波辐射时间、
压强、功率等因素对还原糖收率的影响。实验结果表明,微波辐射条件下,随着硫酸质量分数、固液比、辐射时间、压
强、功率的变化,还原糖收率都存在着一个先增加后减少的趋势。硫酸质量分数2%、液固比15.0、微波辐射时间40
min、压强0.3MPa、功率225.0W,在此条件下玉米秸杆酸水解还原糖收率达到最大值为21.8% 。
