摘要:
在间歇反应釜中,以超低酸(硫酸质量分数为0.05%)水解的方法对5类15种农作物秸秆进行评价,并考察了温度与时间对不同秸秆水解的影响.结果表明:相同条件下,不同种类、同种类不同地区秸秆水解后还原糖浓度有很大差异,这与纤维素、半纤维素及木质素的含量及转化率有关.黑龙江的稻草、玉米秸秆及山东小麦秸秆的还原糖浓度较高,4种棉花秸秆的还原糖浓度都较低;还发现,木质素含量较高的秸秆,超低酸水解还原糖浓度较低,只是水解了部分半纤维素及极少量的纤维素.
Abstract:
The hydrolyses of 15 populations of 5 species of crop straw in a batch reactor under extremely low acid(0.05 wt% sulfuric acid)were evaluated,and the effects of reaction temperature and time on the straw hydrolyses were investigated.The results showed that the concentrations of reducing sugar were different for different species and different populations of crop straw collected in different regions,which was due to the different contents of cellulose,hemicellulose and lignin and their different conversion yields.The rice and corn straw from Heilongjiang,and wheat straw from Shandong had higher reducing sugar concentrations than other populations of crop straw,while the 4 populations of cotton straw had lower reducing sugar concentrations than other populations.It was also found that the higher the content of lignin,the lower the concentration of reducing sugar,and only a portion of hemicellulose and a very small portion of cellulose were hydrolyzed.
