摘要： 基于稻草原料挤压法全组分资源化利用技术,研究了其水解液净化过程的主要工艺,并对水解液的净化效果进行了分析。结果表明,补充水解时间以1h为宜,活性炭用量应为25%,水解液净化后纯度可达95%以上,还原糖损失率低于5%,透光度97.7%,净化后水解液能够满足木糖结晶或通过氢化进行木糖醇生产的还原糖纯度要求。

Abstract: Based on the utilization technology for the whole components from rice straw by extrusion method, the hydrolysate's purifying process and effects were investigated. The results showed that the optimum additional hydrolysis time was 1h, and appropriate amount of activated carbon was 25%. Under these conditions, the purity of hydrolysate reached up to 95%, the loss ratio of reducing sugar was below 5% and the transmittance of hydrolysate was 97.7%. This condition could meet production requirements of xylose or xylitol.

Key words: straw, acid hydrolysate, purify
