The models of fixed bed catalytic reactors in which catalyst deactivation takes place can be significantly simplified by introducing quasi-steady state and constant-pattern travelling wave assumption. This results in faster algorithms. In the present paper the plug-flow, radial dispersion, and well-mixed regions in the series pseudohomogenous models under the above assumptions are discussed. The obtained results are compared with experimental ones in the case of hydrogenation of benzene on a nickel catalyst with thiophene as a poison (irreversible deactivation).
