Abstract: The gasification reaction of coke in a pore was simulated using a cellular automaton method, which was mainly used for the simulation of solidification of steel. It was an adequate method for simulating the phenomenon that the reaction interface was changed with time. Using the developed cellular automaton simulation program, the gasification in a pore of coke was simulated. The simulation conditions were from 1000 to 1400 K for the two kind of pore diameter, 500 μm and 50 μm. Based on the Chapman–Enskog equation and the experimental result of Shigeno, et al., the diffusion coefficient was estimated for two kinds of cokes (m-coke and f-coke). The rate constants for gasification reaction were used on the basis of the results of Kashiwaya, et al. The chemical reaction control was dominant in the pore of 500 μm below 1200 K for m-coke and the diffusion control was over 1400 K. For f-coke, it could be considered as the mixed control in the pore of 50 μm from 1000 to 1400 K, which would be changed from the calculation condition such as a depth of pore, while it was obviously decided as the diffusion control over 1400 K.
