High Performance Catalytic Tubular Membrane Reactors Owing to Forced Convective Flow Operation

Abstract

Various tubular membranes were operated as catalyst supports whereby a radial convective flux of reactants through the pores was generated. A remarkable feature of convective flux through catalytic membranes is the very low catalyst loading necessary for a high conversion. Additionally, this mode of operation allows a control of contact time of the reactants with the catalyst which can improve the reaction selectivity. The influence of catalyst preparation methods was investigated. Very high conversions of H2O2 decomposition could be obtained for production plant waste water over a long period of time. A reactor model was used for simulations of the experiments.
