木质纤维素预处理技术的研究进展

Research Progress on Pretreatment Technologies of Lignocellulose

木质纤维素是多种复杂高分子有机化合物组成的复合体,主要由纤维素、半纤维素和木质素3种主要的聚集体以及一些可溶于极性或弱极性溶剂的提取物组成。在木质纤维素转化为乙醇的过程中,木质纤维素的预处理是关键步骤,对纤维素的水解效率和乙醇的生产成本产生直接影响。为木质纤维素预处理技术的研究和推广应用提供参考,综述了木质纤维素预处理的方法及其效果,并提出了其预处理方法的研究方向。

Lignocellulose is a complex that contains many complicated polymeric organic compounds,mainly cellulose,hemicellulose and lignin,as well as some solubility in polar and weak polar solvent extract.The pretreatment is one of the critical steps in the transformation of lignocellulosic materials to ethanol,which would directly influence hydrolysis efficiency of cellulose and ethanol production cost.The pretreatment techniques of lignocellulose and the effects were summarized,and the development of biomass pretreatment techniques were put forward in this paper.
