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-contain- ing 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 com- prise (1) a porous substrate, (2) an electron-conductive metal, metal oxide or mixture thereof and/or (3) a cata- lyst. 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. Processes described which may be conducted with the disclosed reactor cells and reactors include, for example, the partial oxidation of methane to produce unsaturated compounds or synthesis gas, the partial oxidationof ethane, substitution of aromatic compounds, extraction of oxygen from oxygen-containing gases, including oxidized gases, ammoxidation of methane, etc. The extraction of oxygen from oxidized gases may be used for flue or exhaust gas cleanup.

Abstract: An electrocatalytic process is described for producing unsaturated hydrocarbon compounds from saturated hydrocarbon compounds. The process is conducted in an electrogenerative cell and generally comprises the steps of (A) providing a fuel cell comprising a solid electrolyte having a first surface coated with conductive metal, metal oxide or mixtures thereof capable of catalyzing the reduction of oxygen to oxygen ions, and a second surface coated with metal, metal oxide or mixtures thereof, the two conductive coatings being connected by an external circuit, (B) passing an oxygen-containing gas in contact with the first conductive coating while, (C) passing the saturated hydrocarbon compound-containing feed gas in contact with the second conductive coating, and (D) recovering unsaturated hydrocarbons. In a preferred embodiment, the conductive metal coating on the first and second surfaces comprises a silver-containing metal composition. In another preferred embodiment, the invention comprises a continuous process for the oxidative dehydrogenation of ethane to ethylene and acetylene while generating electricity in an electrogenerative reactor.
