(CN1246384-A)   NOVELTY - The process includes flowing oxygen containing gas through an air passage along a cathode side of an oxygen selective ion transport membrane element at a temperature and oxygen partial pressure effective to separate oxygen contained within the oxygen containing gas into a permeate portion that is transported through the oxygen selective ion transport membrane element to an anode side and a retenate portion that is retained on the cathode.    USE - Used for producing a product gas, e.g. syngas or unsaturated hydrocarbon, in a reaction through an endothermic steam reforming reaction.    ADVANTAGE - Provides syngas having H2/CO molar ratio requiring more heat than is available from the balance of exothermic and endothermic reactions.
