摘　　要：综述了近几年来木素化学解聚产物特征及机理的研究进展,简要介绍木素大分子形成过程、结构单元、连接方式及三相产物(液相、气相、固相)在热液解聚、加氢解聚、催化氧化解聚等解聚工艺下的得率、组成成分等特征,重点介绍了液相产物在不同木素来源、不同解聚工艺下的得率及组成成分等特征,并介绍了化学解聚产物的解聚机理。最后,总结了当前木素化学解聚过程中存在的问题,提出了未来木素解聚研究方向,展望了木素利用的发展前景。The research progress in recent years on the characteristics of lignin’s chemical depolymerization products and the depolymerization mechanism were reviewed in this paper. Brief introduction was made of the lignin macromolecule formation process, structure unit, connecting way and the yield, composition, and of the characteristics in three-phase product （liquid phase, gas phase and solid phase） by hydrothermal depolymerization and hydrogenation depolymerization and catalytic oxygen depolymerization processes. The characteristics of liquid-phase product by the process of different sources of lignin and different depolymerization methods were mainly discussed; the mechanism of chemical depolymerization was also reviewed. Finally, the existing problems in the current lignin’s chemical depolymerization process were summarized, the forthcoming research direction for lignin depolymerization was put forward and the development of lignin utilization was prospected.
