CO Oxidation in a Carberry Reactor: Manifestation ot Reaction Kinetics by Controlled Reaction/Transport.

Abstract

An attempt was made to investigate the coupling of kinetics and external mass transfer in experimental data obtained from a specially designed Carberry type reactor. The reactor used was a spinning basket catalytic reactor where the catalyst (Pt, Rh over γ-Al 2 O 3 , on monolithic ceramic substrate) rotated in the reacting gas stream. This particular configuration enables the experimental measurement of catalytic reaction rate as a function of reacting gas velocity through monolithic catalyst and the estimation of external mass transfer rates in monoliths is thus possible. A proper mathematical model which includes intrinsic kinetics and external mass transfer was used. In this way, intrinsic kinetics of carbon monoxide oxidation have been estimated in order to elucidate the important kinetic parameters and the influence of external mass transfer
