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

## Abstract Analysis of singleβpore behavior in a porous pellet of reactant is used to develop a new model for predicting the conversionβtime relationship for gasβsolid noncatalytic reactions. The model accounts for the influence of pore diffusion, diffusion through the product layer which builds u
