A reactor using dense mixed ion electron conducting membranes was successfully studied in the oxidative dehydrogenation of ethane to ethylene. Already bare Ba0.5Sr0.5Co0.8Fe0.2O3-delta membranes allowed reasonable operation with yields beyond state-of-the-art steam cracking. The application of a surface catalyst was found to enhance performance even further. Long term stable operation and ethylene yields of about 75% were obsd. when using membranes with V/MgO micron grain or Pd nano cluster modified surfaces at temps. of 1040 or 1050 K, resp. Being one key factor for the performance of the membrane reactor, the influence of the surface catalysts on the oxygen permeation is reported in a detailed study.
