As a carbon–neutral fuel, biomass plays a prominent role in replacing fossil fuels. The objective of this research is to uncover the influence of pyrolysis temperature on the metallurgical properties of biochar, as well as to provide a theoretical reference for the preparation of biochar suitable for blast furnace injection. The metallurgical properties of biochar have been systematically studied through the comparative analysis of the physical and chemical properties of biochar. The results show that pyrolysis technology can effectively improve the fuel performance of biomass. As the pyrolysis temperature increases, the fuel performance of biochar increases, the carbonization degree gradually increases, and the combustion performance and reactivity gradually weaken, approaching carbonaceous materials. The Coats-Redfern kinetic equation is used for the kinetic fitting of the combustion process of biochar, and has achieved good results. This clarifies the speed control link in the combustion process of biochar.
