In this study, coke strength for actual microscopic structures before/after solution loss reaction is numerically evaluated using digital-image based modeling. Stress analyses for microscopic structures of coke before/after solution loss reaction in 1173K 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 increases with an increase in conversion for solution loss reaction. It is caused by decrease of pore wall thickness by solution loss reaction. The stress distribution closely relates to change of microscopic structures by solution loss reaction.
