Catalytic membranes without separative function have successfully been applied as microstructured reactors. If the reactant mixture is forced to flow through the pores of a catalytic membrane, the intensive contact allows for high catalytic activity with negligible mass transport resistances. In this work anodized alumina membranes with very uniform pore channels are examined for their applicability as catalytic reactors for gas phase reactions. A reactor model for selective gas phase reactions is set up, taking into consideration microflow effects and pore size distribution in order to quantify their influence on pressure drop, conversion and selectivity.
