To predict coke gasification reactivity, a weight loss of pulverized coke during gasification was measured using a thermogravimetric analysis and the measured data was fitted by the grain model considering particle size distribution of coke. As a result, in CO2 and H2O gasification, reaction rates calculated by the model approximately corresponded to those obtained by the experiments, and activation energies and orders of magnitude of frequency factors were independent of the particle size of coke. Those results suggested that the model can reasonably estimate the reactivity of coke.
