| Abstract: | Microwave pyrolysis of biomass has the advantages of fast reaction rate and high energy utilization, but there are problems such as low product selectivity and low quality. Combined with the use of catalysts, it has the application potential for preparing high-value products. In this paper, the research progress of microwave catalyzed pyrolysis of biomass is reviewed, and the mechanism of microwave catalyzed pyrolysis, the reaction system, and the effects of pyrolysis products on the preparation of high value-added products are introduced. The mechanism of microwave catalytic pyrolysis is briefly described. The microwave catalytic pyrolysis system is discussed from three aspects of raw materials, microwave absorbers and catalysts. The difference in product yields of different types of raw materials and the difference in product selectivity of different catalysts are introduced. Different methods for improving product yield and selectivity are analyzed, and it is pointed out that optimizing and improving catalyst characteristics to make it have compound function, developing large-scale microwave reactor, product directional enrichment and conversion are still problems that need to be solved. It provides a reference for the production of hydrocarbon-rich bio-oil, high-performance bio-char and other products, and then promote to industrial applications. |
