Characteristics of Biomass Devolatilization and in Situ Char Gasification Tested by the Non-Isothermal Method

This work examined the reaction behavior and kinetics of in situ char gasification and the corresponding biomass devolatilization by TGA based on the non-isothermal method. Four kinds of devolatilization atmosphere (N2, N2+CO2 (10%), N2+CO2 (50%), N2+steam (10%)), three kinds of gasification atmosphere (N2+CO2 (10%), N2+CO2 (50%), N2+steam (10%)), and different heating rates (5, 10, 20, 30, 40 K/min) were adopted. With the increase of heating...
