The general mathematical model of CO oxidation reaction over Pd-zeolite catalyst

A new distributed mathematical model of reaction of CO oxidation over Pd-ze olite catalyst is presented. The model takes into account passing of the re actant flow through the catalyst layer, diffusion in pores of zeolite matri x, reaction on the surface of embedded Pd clusters, heat effect of the reac tion, heat and mass transfer across the catalyst layer. Reaction on the Pd clusters is described by the new point model suggested herein. The model ad mits the existence of regular, chaotic and mixed-mode oscillations at the v alues of the parameters close to the experimental conditions. (C) 2001 Else vier Science B.V.
