To investigate the effect of bubble generation in carbonization on pore wall thickness of coke and coke strength, a coke model reproducing pore generation process was developed by random arrangement of spherical bubbles in coke matrix. For the coke models, pore wall thickness was evaluated by an image processing, and stress analyses were performed. As a result, the strength represented a minimum value as the bubble diameter increases. This is because that the small bubble would form uniform porous structure, whereas the large one would produce thick pore wall. Therefore, it is suggested that there is a size of bubbles, which form the pore structure with nonuniform arrangement of pores and this pore wall.
