木质素的预处理和工业应用的新进展

木质素是自然界中仅次于纤维素的可再生复杂天然高分子化合物原料,因其产量巨大,长期以来被视为有发展前途的生物质材料,但由于木质素本身结构的复杂性,导致其在预处理过程和工业应用中存在诸多问题与困难。文章重点关注并归纳了近年来在木质素提取方法及工业应用方面的新进展与新思路：在预处理过程中,研究人员使用物理和生物技术,尝试了多种绿色环保的预处理手段;在工业应用中,随着人们对木质素结构认识的深入,很多新的结构性能得到了应用,为木质素的工业化应用提供了新的方向。

The Pretreatment and New Development of Lignin in Industrial Application

Lignin is the second natural macromolecular materials whose amount is only less than the cellulose.It is considered to be the future development of the biomass materials.There are all kinds of problems in purification and industrial applying because of the complex structure of lignin.This paper introduces some new solutions in lignin’s pretreatment and industrial application at the present stage.According to the references,researchers combined biotechnology with physical methods in the lignin’s pretreatment process for more environment friendship.In the industrial applying facet,various new properties were developed,because of more understanding about the structure of lignin.These new properties will provide new developing directions for lignin’s application in industrialization.
