- Abstract:
- The pyrolysis characteristics of Jianfanggou(JFG) coal was studied using a thermo-gravimetric analyzer and the pyrolysis kinetic parameters were calculated at the different heating rate. The results showed the DTG curves under different heating rate had three peaks and the corresponding temperature were 100℃ , 470℃ and 750℃, the pyrolysis process can be divided into three stages conclusively. The maximum weight loss rate at 470℃ indicated the major weight loss occurred in the second stage. The Tb, Tf and T∞ obtained under experiment situation. The results of the JFG coal pyrolysis kinetic showed the Tb, Tf and T∞ increased gradually with the accretion of the heating rate. In the meantime, the variation of frequency factor was consistent with the trend of activation energy.
