【Abstract】 Biomass pyrolysis can produce high-grade energy products such as biochar, biogas and biooil, which has the advantages of high efficiency and multi-product utilization. However, the products obtained from direct pyrolysis with poor quality are inconducive to realizing high-value utilization. It is urgent to regulate and optimize the process of biomass pyrolysis. Starting from the optimization strategies for pyrolysis reactions, this review systematically outlined the influences of feedstock selection,pretreatment, pyrolysis parameters, reactor types, catalysts, and auxiliary techniques on the pyrolysis conversion process. Additionally, the methods for pyrolysis reaction optimization and product regulation were comprehensively summarized. To realize the green, low-carbon and value-added utilization of biomass, the regulation of pyrolysis products was reviewed from three parts: directional preparation of hydrogen-rich syngas, selective tuning of hydrocarbon liquid fuel, biochar structure tailoring and highvalue utilization. Finally, the challenges and development prospects of biomass pyrolysis were summarized. The introduction of mhachine learning methods to accelerate the development of pyrolysis was also discussed, providing an important reference for the efficient pyrolysis conversion of biomass.更多还原
