Modelling forced periodic operation of catalytic reactors

Abstract

The kinetic adsorption/desorption or AD models used to predict product selectivities obtained through forced-feed concentration cycling have been re-examined. Selectivity improvement results from model structure and nonlinear rates of reaction. The relaxed-steady state bound to periodic operation was found to be predictable from steady state rates for the kinetic model used. Adsorption/desorption models predict no rate improvement for periodic operation. Also they fail to predict experimental observations that are now fairly extensive. © 1982.
