Based on a general classification and characteristic comparison of the existing models, a new model for non‐catalytic gas‐solid reactions is proposed and a general formulation for the model in terms of the solid conversion, X , is presented in mis paper. The model, referred to the generalized model, is demonstrated to be applicable to any solid reactant of general structure ranging from highly porous to nonporous materials. It is shown that the generalized model incorporates the grain and pore structure for a solid pellet and can be reduced to the grain and random pore models as extreme cases.
