## Abstract Analysis of single‐pore behavior in a porous pellet of reactant is used to develop a new model for predicting the conversion‐time relationship for gas‐solid noncatalytic reactions. The model accounts for the influence of pore diffusion, diffusion through the product layer which builds u

✦ Synopsis
A parallel plate model is suggested for describing noncatalytic gas-solid reactions. Based on this model, expressions are developed which relate explicitly the progress of the reaction to porosity of the solid matrix, diffisivities in the pore and in the ash, reactant concentrations in the gas phase and in the solid, as well as the reaction rate-constant.
