• Mechanisms of the breakage and fines generation of cokes after gasification reaction were studied standing on the basic viewpoints as follows:1) The coke is a compound of plural kinds of coke textures with respective strength and reactivity and both the strength and reactivity of coke in total are dominated by the coke textures composition and pore volume fraction.2) The change in the strength after gasification reaction is caused by the change in the coke textures composition and pore volume fraction due to the gasification reaction.According to the basic viewpoints, a mathematical model was developed which calculates the change in the coke textures composition and pore volume fraction during gasification reaction and predicts the strength of coke after gasification reaction.Experiments were made on the gasification and size degradation of cokes using five kinds of coke samples with different coke textures composition and the model was confirmed useful to predict the reaction rates and the strengths after gasification reaction.
