In order to investigate the CO2gasification reaction characteristics from Yuanbao candle coal char,a self-made high dose thermobalance and isothermal thermogravimetry technology were applied to the lump coal char-CO2gasification experiments within 800 ~1 100 ℃. The results showed that when the temperature was below 1 000 ℃,the temperature would be less affected to the reaction rate.At the initial time of the reaction,the gasification rate was low,would be steadily increased and then steadily reduced in tendency with the time passed and the variation range would be small. When the temperature was over 1 000 ℃,the gasification rate would be varied obviously with the temperature,would reach at the max value at the initial period of the reaction and then the reaction rate would be steadily reduced. A mixed reaction model was applied to the processing of the experiment data. The activation energy of the CO2gasification obtained with Yuanbao candle coal was 96. 8 kJ /mol. Meanwhile the activation energy of the CO2gasification calculated with the isoconversional method was 84. 3 ~ 117. 5 kJ /mol. The calculation results of the two methods were fitted. The kinetics model of the CO2gasification reaction could be preliminarily met with the mixed reaction model.
