In this study, coke strength for an actual microscopic structures before/after solution loss reaction is numerically evaluated using image based modeling. Stress analyses for microscopic structures of coke before/after solution loss reaction at 1173 K are carried out. In the analyses, microscopic structure of coke is assumed to be composed of active components and pores. Analytical results show that the maximum von Mises stress sharply increases with an increase in conversion for solution loss reaction. It is caused by decrease in both pore wall thickness and a reduction in the connection of coke texture by solution loss reaction. The stress distribution closely relates to change of microscopic structures by solution loss reaction.
