 This study examined the effects of pyrolysis temperature on the physical and chemical characteristics of apple tree branch biochar, ATB. Results showed that increasing pyrolysis temperature led to an increase in fixed carbon content in organic mineral content, and ash content while it resulted in a decrease in volatile matter content, organic matter content, and cation exchange capacity. Additionally, pyrolysis temperature had a significant impact on the pH value, acidic functional group content, and basic functional group content. Finally, the BET surface area and pore volume of biochar increased with pyrolysis temperature, which indicates that pyrolysis temperature plays an important role in determining the structural and physical chemical properties of biochar.
