In the previous paper, it was demonstrated that the reaction could be divided into three regions, and the modified double shrinking core model, the double shrinking core model and the shrinking core model were applied to regions I, II and III respectively. However, the influence of different conditions on coal particle size change is not fully understood.<BR>In the present paper, the influence of reaction temperature on changes in residue weight, particle size and density was examined, using Taiheiyo coal screened to 16/20 mesh as the starting materials. It was found that the effect of reaction temperature on coal particle change is very great in region I. Moreover, by assuming initial particle size using the double shrinking core model, the relation between reaction temperature and particle size change was clarified.
