The performance of a mathematical model for transport, reaction, and structure evolution during gas-solid reactions involving porous solids and solid product was evaluated using experimental reactivity evolution data for the sulfidation of porous zinc oxide and the sulfation of limestone calcines.

## 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
