农作物秸秆超低酸水解的比较
Comparative study on crop straw hydrolysis under extremely low acid
摘要
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.关键词
