Notes:
The commonly employed internal isothermal model for gas-solid catalytic reactions, wherein the pellet is assumed internally isothermal but with internal concentration gradient, is justified by analyzing the full non-isothermal diffusion-reaction equations as an appropriate perturbation problem (β small, and Bih/β finite). The internal isothermal model is shown to be the zeroth order solution of the perturbation problem. Analytic expressions for the first order corrections are given for a first order reaction.
