杂交狼尾草碱预处理研究
Study on Different Alkali Pretreatment of Hybrid Pennisetum
摘要
Abstract
In order to investigate the changing of main components in Hybrid Pennisetum before and after the alkali pretreatment,different alkali of pretreatment of Hybrid Pennisetum were used.By the solid -state chemical pre treatment method,the pretreatment of Hybrid Pennisetum by sodium hydroxide,calcium hydroxide,ammonia and urea are studied.The contents of cellulose;hemicellulose and lignin were analyzed by Paradigm fiber washing method.The results showed that the contents of acid detergent fiber,neutral de-tergent fiber and hemicellulose decreased significantly after pretreatment.When the concentration of NaOH was 8%,the content oflignin was 5.28%;When the concentration of Ca(OH)2 was 2%,the content oflig-nin was 5.68%;When the concentration of ammonia was 8%,the content oflignin was 5.12%;When the concentration of urea was 6%,the content oflignin was 4.38%,which was best in the four pretreatments.关键词
