To provide the heat required to drive the endothermic steam reforming reaction, a low grade fuel is combusted in a reactor and the heat of combustion conducted to the endothermic reaction. By using an oxygen selective ion transport membrane element to transport the oxygen required for combustion, the formation of undesirable NOx compounds is minimized.

[ What is claimed is:] [4.]4. A process for providing heat to an endothermic reforming reaction inside a reaction passage, comprising:transporting a permeate portion of oxygen through an oxygen selective ion transport membrane element from a cathode side thereof located within a combustion passage to an anode side located within said reaction passage so that a retentate portion is retained on said cathode side;flowing an oxygen containing gas through an air passage separated from said combustion passage by a second oxygen selective ion transport membrane element, said second oxygen selective ion transport membrane element being effective to separate oxygen contained within said oxygen containing gas into a second permeate portion that is transported through said second oxygen selective ion transport membrane element to a second anode side that is adjacent to said combustion passage, thereby to produce the oxygen within the combustion passage forming the permeate portion of the oxygen, and a second retentate portion that is retained on said second cathode side;combusting a fuel within the combustion passage with the oxygen of the second permeate portion, thereby generating a heat of combustion;exothermically reacting part of a constituent of a process gas flowing through said reaction passage with the permeate portion, thereby generating further heat of combustion; andtransferring said heat of combustion and said further heat of combustion to said endothermic reforming reaction.
