Relationship between the change of coke pore structures and caking additive size was investigated by image analyzing of coke cross section. When asphalt pitch (ASP) was pulverized to small size, they were dispersed on coke matrix and large pores which had formed from large ASP particle decreased. The low circularity pores which were mainly composed of connected pore or void around inert particle also decreased by pulverizing ASP. The reason was thought that the probability that gas generated from ASP combines each other decreased and the probability that adhesive force around inert particle was enhanced by ASP increase with wider dispersion.
