Synthesis gas, a mixture of hydrogen and carbon monoxide, can be produced by oxidatively-reforming a hydrocarbon-containing stream which passes on one side of a non-porous, mixed conducting ceramic membrane, with oxygen from a hot, oxygen-containing gas, preferably air, which passes on the other side of the ceramic membrane. These membranes, known in the art generically as ion transport membranes (ITMs), utilize an oxygen chemical potential gradient across the membrane to cause oxygen ions to migrate through the membrane.
