| Summary: | In this paper, co-pyrolysis of stone coal and biomass was performed. The activation energy of pyrolysis was analyzed, and the mechanism of biomass on the stone coal pyrolysis was discussed. The results show that biomass contributed to the pyrolysis of stone coal. The optimum pyrolysis heating rate of the biomass and stone coal was 25 °C/min and 20 °C/min respectively. The alkaline and alkaline earth metals derived from biomass pyrolysis improved thermal decompose of stone coal, yet stone coal inhibited biomass pyrolysis under co-pyrolysis conditions. The promotion of corn stalk on the stone coal pyrolysis was better than that of sawdust. |
