The use of lignocellulosic biomass pyrolysis to produce renewable fuels and high value-added chemicals can help alleviate the energy and resource crisis facing the world today. However, the direct pyrolysis of lignocellulosic biomass encountered some problems. For example, the bio-oil obtained from lignocellulosic biomass pyrolysis has the disadvantages of lower heating value with strong acidity due to the high oxygen contents of biomass. The use of biomass and other types of waste for co-pyrolysis can effectively solve these problems. Among them, the co-pyrolysis of lignocellulosic biomass and plastics has been extensively studied, the co-pyrolysis can not only improve the composition and quality of lignocellulosic biomass pyrolysis liquid products but also realize the reduction and resource utilization of waste plastic waste. This article summarizes the current research status of lignocellulosic biomass and plastic co-pyrolysis technology in recent years, focusing on the synergistic effect of lignocellulosic biomass pyrolysis and plastic pyrolysis, and prospects the development of biomass co-pyrolysis technology. In addition, the article also summarizes the catalysts used in the catalytic co-pyrolysis system of lignocellulosic biomass and plastics and the catalytic mechanisms involved. A comprehensive discussion on the CO₂ emission of co-pyrolysis is presented. This review reveals the application prospects of pyrolysis technology in the pyrolysis of lignocellulose to produce fuels and chemicals, and also proposes future research directions in pyrolysis technology optimization and catalyst development.

利用木质纤维素生物质热解生产可再生燃料和高附加值化学品有助于缓解当今世界面临的能源和资源危机。然而，木质纤维素生物质的直接热解遇到了一些问题。例如，由木质纤维素生物质热解获得的生物油由于生物质氧含量高而具有热值较低、酸性强的缺点。利用生物质和其他类型的废物进行共热解可以有效解决这些问题。其中，木质纤维素生物质与塑料的共热解得到了广泛的研究，共热解不仅可以改善木质纤维素生物质热解液产品的成分和质量，而且可以实现废塑料废弃物的减量化和资源化。本文综述了近年来木质纤维素生物质与塑料共热解技术的研究现状，重点研究了木质纤维素生物质热解与塑料热解的协同效应，并对生物质共热解技术的发展进行了展望。此外，文章还总结了木质纤维素生物质与塑料催化共热解系统中使用的催化剂及其所涉及的催化机理。关于CO的全面讨论 文章还总结了木质纤维素生物质与塑料催化共热解系统中使用的催化剂及其催化机理。关于CO的全面讨论 文章还总结了木质纤维素生物质与塑料催化共热解系统中使用的催化剂及其催化机理。关于CO的全面讨论₂提出了共热解的排放。该综述揭示了热解技术在木质纤维素热解生产燃料和化学品方面的应用前景，并提出了热解技术优化和催化剂开发的未来研究方向。
