Abstract

Current research on biomass pyrolysis in a CO2 atmosphere remains constrained, and there is still a lack of thorough investigation of its complex pyrolysis mechanism, which hinders further advancements in its utilization and development. This study investigates the thermogravimetric analysis, kinetics analysis, and pyrolysis product analysis of pine needles (PNs) pyrolysis under N2 and CO2 atmospheres. Thermogravimetric analysis identified three distinct stages in the PNs pyrolysis process: dehydration, thermal cracking, and carbon decomposition. The application of kinetic methods, including Coats-Redfern, Friedman, and Flynn-Wall-Ozawa, revealed that PNs exhibited a lower activation energy for pyrolysis in a CO2 atmosphere with the D6 kinetic model being the optimal fit. Additionally, pyrolysis product analysis revealed that the presence of CO2 promoted the cracking of volatile organic compounds (VOCs) released during the pyrolysis process and facilitated gas-phase reactions with VOCs to ultimately enhance syngas yield.
