| 摘 要： | 为开发高效、低成本的预处理技术,促进竹子生物质及其废弃物资源的能源化利用,采用3种不同纤维素预处理方法分别对竹子生物质废弃物——笋壳和竹叶(茎)进行比较研究,同时与玉米秸秆相比较.结果表明,在稀H2SO4–酶解工艺、浓H3PO4–酶解工艺和NaOH–酶解工艺条件下,几种样品水解液中分别存在3、4和5种糖类组分.在稀H2SO4–酶解工艺中,木糖为主要成分,其次为葡萄糖;在浓H3PO4–酶解工艺中,葡萄糖为主要成分,其次为木糖;而在NaOH–酶解工艺,葡萄糖和木糖含量基本相当.同时对样品处理前后的表面结构变化分析表明,不同处理工艺均改变了竹叶(茎)、笋壳和秸秆等样品的表面结构,其结构更为松散,从而有利于纤维素的酶解.

| Abstract: | Higher-efficiency and lower-cost pretreatment methods for bamboo and its residues are important in energy utilization.In this study,two kinds of bamboo residues(bamboo shoot shell) fiber and bamboo stem and leaf were pretreated by three methods,and the treatments were compared with those for corn stalk.The results indiciated that 3,4 and 5 kinds of sugar existed in the hydrolyzates under the different pretreatments,that is,H2SO4-cellulase,H3PO4-cellulase and NaOH-cellulase technologies,respectively.With the... |
