The effects of the cooling and/or air exposure of coal char on the gasification reactivity of the char were investigated in a fixed-bed flow reactor under some temperatures. The cooling was found to be the main respect degrading the gasification reactivity of the char. The results of TPD experiment show that the reactivity degradation could be attributed to the decrease in active sites of the char.
