Abstract: There is provided a process for the net catalytic oxidative dehydrogenation of alkanes to produce alkenes. The process involves simultaneous equilibrium dehydrogenation of alkanes to alkenes and combustion of the hydrogen formed to drive the equilibrium dehydrogenation reaction further to the product alkenes. In the present reaction, the alkane feed is dehydrogenated over an equilbrium dehydrogenation catalyst in a first reactor, and the effluent from the first reactor is then passed into a second reactor containing a reducible metal oxide which serves to selectively combust hydrogen in an oxidation/reduction (REDOX) reaction. This particular mode of operation is termed a separate reactor, REDOX mode.

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.
