Abstract: An individual solid oxide cell (SOC) constructed of a sandwich configuration including in the following order: an in oxygen electrode, a solid oxide electrolyte, a fuel electrode, a fuel manifold, and at least one layer of mesh. In one embodiment, the mesh supports a reforming catalyst resulting in a solid oxide fuel cell (SOFC) having a reformer embedded therein. The reformer-modified SOFC functions internally to steam reform or partially oxidize a gaseous hydrocarbon, e.g. methane, to a gaseous reformate of hydrogen and carbon monoxide, which is converted in the SOC to water, carbon dioxide, or a mixture thereof, and an electrical current. In another embodiment, an electrical insulator is disposed between the fuel manifold and the mesh resulting in a solid oxide electrolysis cell (SOEC), which functions to electrolyze water and/or carbon dioxide.

Abstract: A reforming process and apparatus exhibiting improved catalyst longevity towards reforming a high sulfur-containing liquid fuel. The process involves contacting in a first reforming zone a first oxidant and a liquid fuel containing high molecular weight organosulfur compounds with a partial oxidation catalyst under CPOX reaction conditions to form a first reformate stream containing a mixture of unconverted and partially-converted hydrocarbons and one or more low molecular weight sulfur compounds; and then contacting in a second reforming zone the first reformate stream with steam and optionally a second oxidant in the presence of an autothermal reforming catalyst under ATR reaction conditions to form a second reformate stream containing carbon monoxide and hydrogen and one or more low molecular weight sulfur compounds. The low molecular weight sulfur compounds can be readily removed from the first and/or second reformate streams by gas phase adsorption methods.

Abstract: A Sabatier process involving contacting carbon dioxide and hydrogen in a first reaction zone with a first catalyst bed at a temperature greater than a first designated temperature; feeding the effluent from the first reaction zone into a second reaction zone, and contacting the effluent with a second catalyst bed at a temperature equal to or less than a second designated temperature, so as to produce a product stream comprising water and methane. The first and second catalyst beds each individually comprise an ultra-short-channel-length metal substrate. An apparatus for controlling temperature in an exothermic reaction, such as the Sabatier reaction, is disclosed.
