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 wa

Works of the author with colleagues devoted to performance of catalytic processes in forced unsteady-state conditions in reactors with fixed bed of catalyst are briefly reviewed. Special attention is paid to periodic change of direction of reaction mixture passingthroughthe catalyst bedreverse-proce
Periodic operation of a catalyst pellet can produce greater selectivity than steady-state operation even when diffusional mass transfer resistance is very large. For the example discussed here improved selectivity is obtained at a switching frequency which is small enough to provide adequate penetra
