C01B 326

US Classification:

252373, 423652, 423650, 423651, 4234182

Abstract:

An exothermic reaction and an endothermic reaction are thermally combined in a reactor having at least one oxygen selective ion transport membrane that provides the exothermic reaction with oxygen from an oxygen-containing gas such as air. The thermal requirements of the endothermic reaction are satisfied by the exothermic reaction. Dependent on the reactor design employed, the exothermic and endothermic reactions may be gaseously combined.

International Classification:

F16J 1502

US Classification:

277630, 277650

Abstract:

A joint assembly for joining a ceramic membrane of tubular form to a tube sheet used in supporting the ceramic membrane within a reactor. The ceramic membrane is received within a fixture connected to the tube sheet and a follower, extending into the fixture, exerts a force on a high temperature sealing element located between the fixture and the ceramic membrane to effect a seal and to hold the ceramic membrane in place. The force can be exerted directly on the sealing element or on the ceramic membrane itself.

International Classification:

B01D 5322

US Classification:

95 54, 423579, 204295, 96 6, 96 11

Abstract:

The invention relates to a process for the production of oxygen using novel membranes, formed from perovskitic or multi-phase structures, with a chemically active coating which demonstrate exceptionally high rates of fluid flux. The process uses membranes that are conductors of oxygen ions and electrons, which are substantially stable in air over the temperature range of 25Â C. to the operating temperature of the membrane.

US Classification:

204295, 204265, 204266, 428469, 428697, 428701, 428702

Abstract:

Solid membranes comprising an intimate, gas-impervious, multi-phase mixture of an electronically-conductive material and an oxygen ion-conductive material and/or a mixed metal oxide of a perovskite structure are described. Electrochemical reactor components, such as reactor cells, and electrochemical reactors are also described for transporting oxygen from any oxygen-containing gas to any gas or mixture of gases that consume oxygen. The reactor cells generally comprise first and second zones separated by an element having a first surface capable of reducing oxygen to oxygen ions, a second surface capable of reacting oxygen ions with an oxygen-consuming gas, an electron-conductive path between the first and second surfaces and an oxygen ion-conductive path between the first and second surfaces. The element may further comprise (1) a porous substrate, (2) an electron-conductive metal, metal oxide or mixture thereof and/or (3) a catalyst. The reactor cell may further comprise a catalyst in the zone which comprises a passageway from an entrance end to an exit end of the element.

Abstract:

An apparatus for separating oxygen from an oxygen-containing gas and facilitating a chemical reaction with the separated oxygen includes a mixed conducting membrane, a porous body, and a material for catalyzing the reaction. The mixed conducting membrane has respective oxidation and reduction surfaces and is made of a non-porous, gas-impermeable, solid material capable of simultaneously conducting oxygen ions and electrons. At least the membrane and the catalyzing material are non-reactive with each other or are physically separated from each other during oxygen separation and the chemical reaction. The apparatus can be embodied by tubes, and a plurality of such tubes can form part of a reaction vessel in which various chemical reactions can occur benefiting from the apparatus design.
