PYROLYSIS OF SHENMU COAL MACERALS AND KINETICS ANALYSIS
Pyrolysis of Shenmu coal maceral concentrates under different conditions was systematically investigated in TG-151 pressurized thermal balance.The pyrolysis kinetics was analysed by using Distribution Activation Energy Model (DAEM).The results indicated that vitrinite has higher yield of volatile matter than fusinite.With increasing temperature,the yield of volatile matter of vitrinite and fusinite increased.Pyrolysis pressure and heating rate showed little effect on the yield of volatile matter of macerals.The kinetic result illustrated that vitrinite has lower activation energy than fusinite.
