摘要: 本研究采用球磨法对产氢用生物质进行预处理,以酶解后还原糖得率作为考察指标,采用电镜对粉碎后物料进行分析,并利用DPS 7.05分析软件进行试验设计和数据分析,对球磨处理工艺进行优化。分析了原料初始粒径、球料比和球磨时间对酶解糖化过程的影响,得出球料比为显著影响因素,球磨预处理最佳工艺参数为:原料初始粒径 0.45 mm,球料比20∶1,球磨时间 1 h,在此条件下,还原糖得率为 74.50%。

关键词: 生物质, 还原糖得率, 粒径, 球料比, 球磨时间

Abstract: In this study, ball milling was used to pretreat the straw biomass in hydrogen production process, the reducing sugar yield was taken as reference. After being smashed the material was observed under scanning electron microscope. In order to optimize the ball milling pretreatment process; DPS analysis software was used to design experiments and analyse the data. The influences of the initial raw material particle size, ball to powder weight ratio and ball milling time on the enzyme saccharification processing were analyzed. It was found that the significant influence factors were the ratio of ball to powder weight. The optimal parameters of ball milling pretreatment were as follows: raw material initial size of 0.45 mm, 20∶1 ratio of ball to powder weight ratio, milling time of 1 h, under this condition, the reducing sugar yield was 74.50%.

Key words: biomass, reducing sugar yield, grain size, ratio of ball to powder weight, milling time
