Development of coke production technology which can maintain high coke strength with use of certain amount of high rank coal is needed. Accordingly, it is important to investigate influence of coke pore structure on coke strength and dominant factors of coke strength. In this study, results of three-dimensional analysis such as components of coke structure and Mises stress of two types of high strength coke will be presented. Three-dimensional composition of coke was successfully visualized and quantified by three-valuation method. Moreover, three-dimensional stress analysis was conducted to investigate the relationship between coke structure and coke strength.
