木质纤维素预处理实现组分综合利用OACSTPCD

With the development of degradable materials in related fields,the materialization and comprehensive utilization oflignocellulose attracted great interest in recent years.Upon pretreatment of lignocellulose,nearly single components of cellulose,hemicellulose and lignin can be obtained through various separation and purification methods.More importantly,these pure components and their derivatives can be further used in chemical,material,biomedical fields and so on.In this review,we summarized different pretreatment methods including physical methods,chemical methods,biological methods,physical and chemical methods and combined pretreatment methods.Due to the stubbornness of complex lignocellulose structure,these pretreatment methods were mainly focused on their potential influence on the subsequent comprehensive utilization process.Moreover,we described the chemical modifications of single components from separation and purification,as well as the application of their derivatives,hoping to provide guidance for the development of different lignocellulosic utilization paths.
