β¦ Synopsis
Exact (numencal) and approxunate semi-analytical solution procedures are developed to mvestlgate the problem of multlcomponent dlffuslon accompamed by multiple reactions m porous catalyst pellets Examples are presented to illustrate the apphcatlon of the proposed procedures and to compare exact and approximate solutions In certain circumstances It 1s found that reactants can diffuse m the dlrectlon m which then concentration increases

The effect of internal diffusion on dehydration of methanol on model pellets of porous catalyst (sulfonated stymm-divinylbenzene ion exchange resin) was studied experimentally. The results proved that bulk diffusion of a multicomponent reaction mixture in a porous catalyst can be satisfactorily desc
Unidirectional diffusion and flow of O,-CO-CO, gas mixtures undergoing heterogeneous chemical reaction within a porous CuO-on-alumina plug flow reactor are investigated. Experimental data for spatial distributions of pressure, temperature and composition and for feed-end species fluxes exhibit reaso
