A method for maintaining the temperature of an oxygen-selective ion transport membrane within a desired temperature range includes providing an ion transport reactor with the oxygen-selective ion transport membrane. An oxygen-donating feed gas is delivered to a cathode side at a first temperature, at a first rate, and at a first oxygen partial pressure and a reactant gas is supplied to an anode side at a second temperature and a second rate. A physical condition is then established within the ion transport reactor that favors the transport of elemental oxygen through the oxygen selective ion transport membrane as oxygen ions. One or more process variables are then regulated to maintain the temperature of the oxygen selective ion transport membrane within the desired range.

[ We claim:] [1.] A method for maintaining the temperature of an oxygen-selective transport membrane, contained within an ion transport reactor, within a desired temperature range which comprises:a) providing the ion transport reactor with said oxygen selective ion transport membrane that has a cathode side and an anode side;b) delivering an oxygen-donating feed gas at a first temperature, at a first rate, and at a first oxygen partial pressure to said cathode side;c) supplying a reactant gas to the anode side at a second temperature and at a second rate, said reactant gas being capable of reacting with oxygen;d) establishing a physical condition within said ion transport reactor that favors transport of elemental oxygen through said ion transport membrane as oxygen ions;e) transporting elemental oxygen obtained from said feed gas through said ion transport membrane as oxygen ions to provide transported elemental oxygen to said anode side; andf) regulating one or more process variables to maintain said temperature of said ion transport membrane within said desired temperature range.
