A power consumption equation for coke degradation was established based on the two kinds of quintessential volume hypothesis which was the theory about energy-size of comminution. The effect of gasification reaction and temperature on energy consumption of coke degradation was analysed by gasification and high temperature compressive experiments. The energy conversion between the external mechanical work and internal energy of cokes was analyzed by high temperature compressive experiments, and then the parameter of temperature was introduced into the power consumption equation. The degradation rate of gasified coke at different temperatures were predicted by the improved power consumption equation. The results showed that the coke degradation rate was significantly affected by the input power which has a greater impact on the more reacted cokes, and the drum experiment was conducted to verify the applicability of power consumption equation for gasified coke degradation at room temperature. The temperature has a significant influence on the coke degradation behavior, and the more input power for the system, the greater the influence of temperature on the gasified coke degradation.
