A process to generate an enhanced output of a desired product from an ion transport reactor utilizes the reaction products from both the cathode side and the anode side of an oxygen selective ion transport ceramic membrane. An oxygen donating first feed stream containing the desired product in a chemically bound state is delivered to the cathode side while an oxygen accepting second feed stream is delivered to the anode side. Following chemical reactions on both the cathode side and the anode side, a desired product is recovered from a first product stream exiting from the cathode side and from a second product stream exiting from the anode side such that the sum of the desired product contained within the two product streams exceeds that attainable from either product stream alone.

[ We claim:] [1.] A process for generating an enhanced output of desired product from an ion transport reactor, comprising:a) providing the ion transport reactor, the ion transport reactor having a product oxygen-selective ion transport membrane, a reaction space, and a further oxygen-selective ion transport membrane, each of the product and further oxygen-selective ion transport membranes having a cathode side and an anode side, the anode side of each of the product and further oxygen-selective ion transport membranes being located within the reaction space;b) delivering an oxygen-donating first feed stream containing the desired product in a chemically bound state at a first oxygen partial pressure to said cathode side of said product oxygen-selective ion transport membrane while simultaneously delivering an oxygen-accepting second feed stream to said reaction space and an oxygen containing feed stream containing oxygen in a chemically unbound state to said cathode side of said further oxygen-selective ion transport membrane;c) operating said ion transport reactor with said product and further oxygen-selective ion transport membranes at an elevated temperature sufficient to facilitate oxygen ion transport through said product and further oxygen-selective ion transport membranes;d) transporting elemental oxygen obtained from said first feed stream through said product oxygen-selective ion transport membrane to react with a portion of said second feed stream so that said desired product is produced at the cathode side of said product oxygen-selective ion transport membrane and another product is produced within said reaction space by way of chemical reactors that are on-balance endothermic;e) reacting the oxygen transported through the further oxygen-selective ion transport membrane with a further portion of said second feed stream in an exothermic oxidative reaction to thermally balance said chemical reactions so that a sum thereof is energy neutral; andf) recovering a first product stream containing a first portion of said desired product from said cathode side, and recovering a second product stream from said reaction space.
