ABSTRACT:
There is provided a process for the selective combustion of hydrogen using a membrane structure containing metal oxides, such as bismuth oxide, that can selectively oxidize hydrogen in the presence of hydrocarbons by virtue of their lattice oxygen. A hydrocarbon/hydrogen containing gas and an oxygen-containing gas, such as air, are passed on separate sides of the membrane. The lattice oxygen is continuously being replenished by air oxidation. The selective hydrogen combustion reactor can be used in dehydrogenation processes as an interstage heater and as a hydrogen scavenger for olefin yield maximization.
