Abstract

Lignocellulose is the main component of plants and has a wide range of sources. The high-value production of lignocellulose lies in the biorefinery of lignin, cellulose and hemicellulose. The advantages and disadvantages of traditional lignocellulose pretreatment methods were summarized, and the effective pretreatment parameters were listed. As a green solvent system with excellent performance, deep eutectic solvents (DES) are considered to be the most potential biomass pretreatment system. Based on this, the new trend and progress of DES in lignocellulose pretreatment were reviewed, focusing on the effects of distinct kinds of lignocellulose raw materials, distinct components of DES, distinct reaction conditions and assisted by microwave ultrasound on the pretreatment of lignocellulose, and the recyclability of DES solution system was discussed. Finally, the application and development direction of DES in lignocellulose pretreatment are proposed and prospected.

木质纤维素深层共晶溶剂预处理及相关技术综述

木质纤维素是植物的主要成分，来源广泛。木质素、纤维素和半纤维素的生物精制是木质素高价值生产的关键。总结了传统木质纤维素预处理方法的优缺点，列出了有效的预处理参数。深共晶溶剂(DES)作为一种性能优异的绿色溶剂体系，被认为是最有潜力的生物质预处理体系。在此基础上，综述了DES在木质纤维素预处理中的新趋势和进展，重点讨论了不同木质纤维素原料、不同DES组分、不同反应条件和微波超声辅助对木质纤维素预处理的影响，并讨论了DES溶液体系的可回收性。最后，对DES在木质纤维素预处理中的应用及发展方向进行了展望。
