A simple model for the exotherm ic oxidation of a solid re a c ta n t or reaction in a cataly st bed is considered. A gaseous com ponent, e.g. 0 2, diffuses through a porous m edium where it reacts releasing heat. The concentration of th e gaseous species in the surrounding reservoir is held co n stan t as is the surrounding (am bient) tem perature. H e a t tran sfer w ithin th e reaction zone occurs by conduction, leading to an internal te m p eratu re-p o sitio n profile.
