摘要
本文论文优化了桉木片预水解提取半纤维素的工艺,最优条件下,半纤维素的提取率达到48.57%。采用离子色谱分析了桉木预水解液中糖类主要组成。论文选题是生物质精炼领域的热点问题,对桉木预水解工艺优化、预水解液的处理和资源化利用都具有一定的参考价值。
The extraction process of hemicellulose from pre- hydrolysis of eucalyptus wood was optimized in this paper,under the optimum conditions,the extraction rate of hemicellulose could be reached 48. 57%. The main components of sugar in eucalyptus pre- hydrolysis liquid were analyzed by ion chromatography. The topics of this thesis are hot issues in the field of biomass refining,and has some reference value for the optimization of the pre hydrolysis process of eucalyptus and the disposal and utilization of the pre hydrolysis liquid.
