摘要:

生物质是唯一一种可再生碳源,其高效利用是解决能源与环境问题的纽带。近年来,基于化石能源的塑料制品使用和废弃量快速增加,其难于自然降解,对环境造成严重威胁。生物质与塑料的催化共热解技术能够得到选择性更高的产品,进而提升高附加值产物的产率和品质,是生物质与塑料规模化利用的重要方向。本文从生物质与塑料高效转化的角度出发,梳理了生物质与塑料催化共热解技术研究进展,对生物质与塑料共热解机理、ZSM-5基催化剂共热解、过渡金属基催化剂共热解、碱/碱土金属催化剂共热解、多催化剂共热解等不同种类的催化共热解研究前沿进行了综述,并对比了原位催化和非原位催化的共热解方式,展望了生物质与塑料催化共热解的主要技术和发展方向,以期为生物质与塑料的高效协同转化提供方法参考和研究思路。

Abstract:

Biomass is the only renewable carbon source, and its efficient utilization is the link to solve energy and environmental problems. In recent years, waste of plastic products based on fossil energy has increased rapidly because of their huge consumption. However, plastic is difficult to degrade naturally, thus posing a serious threat to the environment. The catalytic co-pyrolysis technology of biomass and plastic can obtain more selective products, and improve the yield and quality of products, which is an important direction for large-scale utilization of biomass and plastic. From the perspective of efficient conversion of biomass and plastic, recent advances on catalytic co-pyrolysis of biomass and plastic were summarized in the paper. Mechanism of co-pyrolysis of biomass and plastic, and advances of the co-pyrolysis with different types of catalyst, such as ZSM-5-based catalyst, transition metal-based catalyst, alkali/alkaline earth metal catalyst, and multi-catalysts, were reviewed. Catalytic co-pyrolysis with in-situ and non-in-situ mode were compared. Prospects for the primary technology and future development direction of catalytic co-pyrolysis of biomass and plastic were pursued, which may provide technical references and research ideas for the efficient synergistic conversion of biomass and plastic.

Key words: biomass, plastic, co-pyrolysis, catalyst, catalytic mode
