In the present study, the CO2 gasification behaviours of the co-pyrolysis chars with coal and biomass as feedstock were investigated using isothermal thermogravimetric analysis (TGA) at 950–1150 °C. The TGA results demonstrated that the char gasification reactivity was improved at higher biomass composition. In addition, the char characteristics results evaluation revealed that biomass promoted the development of a porous structure and inhibited the formation of graphite-like carbon during the co-pyrolysis of coal and biomass. Moreover, an extended random pore model (eRPM) was proposed to define the char gasification kinetics of coal and biomass. It was found that the activation energies of chars decreased with increasing biomass composition. Lastly, the relationship between the gasification reactivity and char characteristics was evaluated. |
