Partial oxidation of ethane : the potential of membrane reactors

Year: 2003

Type: article

Abstract: The operation of packed-bed membrane reactors (PBMR) was compared to the classical fixed-bed reactor (FBR) using the catalytic oxidation of ethane over a γ-Al2O3 supported VOx catalyst (1.4 % V) as a model reaction. Ethylene, CO and CO2 were observed as products in both reactors. Several attractive operation modes for the PBMR were identified, a selective oxidation mode with low oxygen-to-hydrocarbon rations for olefin production, a mode favoring CO production and a deep oxidation mode for catalytic combustion. In all modes conversion in the PBMR is increased relative to the FBR, and the selectivity is enhanced into the desired direction. The better performance of the PBMR in all modes is caused by the interaction of changed concentration and contact time profiles inside the reactor due to the oxidant dosing over the membrane.
