Syngas, a mixture of hydrogen and carbon monoxide is an intermediate in the conversion of methane to liquid fuels. For certain applications it is, desirable to maintain an H2/CO molar ratio of about 3. This molar ratio is achieved by steam reforming of methane in accordance with:, CH4 + H2O ~ 3H2 + CO. 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.
