✦ Synopsis

The effects of external film resistances on the deactlvatlon of a s&e catalyst pellet are exammed Investrgatlons on the Isothermal fouhng are first consldered and are then extended to non-Isothermal fouhng for both endothermic and exothermlc reactlons A pseudo-steady state for the reaction system 1s assumed with Langmu Hmshelwood type of kmetlcs for the mam reactlon whale for fouhng, first order krnetlcs with respect to active sites and the fouling precursor concentration are adopted Orthogonal collocation and a modified col-locatlon+ffectwe reaction zone method are employed to solve the proposed model INTROlNJCTlON
