A process for the production of synthesis gas from light hydrocarbons such as methane includes the net catalytic partial oxidation of a hydrocarbon feedstock by contacting a feed stream comprising the hydrocarbon feedstock and an O -containing gas with a catalyst in a reaction zone maintained at conversion-promoting conditions effective to produce an effluent stream of H and CO in a molar ratio of about 2:1. A preferred catalyst used in the process includes at least one catalytically active metal supported on a catalyst support comprising an aluminum-containing, oxide-dispersion-strengthened, alloy that has been treated to provide a protective oxide layer between the support and the catalytically active metal.

Catalysts comprising a catalytically active metal on a NiOâMgO coated porous metal alloy support that are active for catalyzing the oxidative conversion of methane to CO and H are disclosed. The preferred catalytically active metal is rhodium and the porous metal alloy support is preferably a perforated fecralloy foil. A method of making the catalysts and coated supports, and processes for using the new catalysts for converting light hydrocarbons, such as methane, to synthesis gas, are disclosed.

Methods for fabricating a capacitor are provided. In the methods, a dielectric may be formed on a metal (e. g. nickel) substrate, and a copper electrode is formed thereon, followed by the thinning of the metal substrate from its non-coated face, and subsequently forming a copper electrode on the thinned, non-coated face of the substrate.

A method is disclosed for the catalytic conversion of light hydrocarbons to synthesis gas. The method involves the contacting of a feed stream comprising the hydrocarbon feedstock and an O-containing gas with a catalyst in a reaction zone maintained at conversion-promoting conditions effective to produce an effluent stream comprising carbon monoxide and hydrogen. The preferred catalysts of the invention comprise bulk nickel monoliths that have been activated by heating in a reducing environment. The preferred catalysts convert hydrocarbons to syngas primarily by a predominantly partial oxidation reaction and retain a high level of activity and selectivity to carbon monoxide and hydrogen under conditions of elevated pressure, high gas space velocity and high temperature in a short contact time reactor.

A method is disclosed for converting light hydrocarbons to synthesis gas employing a reduced nickel alloy monolith catalyst which catalyzes a net partial oxidation reaction to produce an effluent stream comprising carbon monoxide and hydrogen in a ratio of about 2:1 H/CO. Preferred catalyst beds comprise a compositionally graded axial array, or stack, of Ni—Cr, Ni—Co—Cr, or Ni—Rh monoliths, and their manner of making is disclosed. The Ni alloy monolith catalysts are mechanically strong and retain high activity and selectivity to carbon monoxide and hydrogen products under syngas production conditions of high gas space velocity, elevated pressure and high temperature.

A method is disclosed for converting light hydrocarbons to synthesis gas employing a reduced nickel alloy monolith catalyst which catalyzes a net partial oxidation reaction. Certain preferred catalysts comprise bulk Ni—Cr, Ni—Co—Cr or Ni—Rh alloy materials. A method of making a bulk nickel alloy catalyst includes depositing a combination of chromium and cobalt metals, or rhodium metal, onto a nickel metal substrate and then thermally diffusing the Cr and Co coating, or the Rh coating, into the atomic lattice of the nickel substrate to produce a bulk Ni—Co—Cr or Ni—Rh alloy monolith catalyst. Preferred 3—D catalyst configurations include perforated foil, metal gauze, metal foam and expanded metal. The catalysts are mechanically strong and self-supporting, and retain high activity and selectivity to carbon monoxide and hydrogen products under syngas production conditions of high flow rate, superatmospheric pressure and high temperature.

Thermally integrated monolith catalysts active for catalyzing the oxidative conversion of methane to CO and Hare disclosed. The composition and multi-layer configuration facilitates heat balancing between exothermic and endothermic reactions that take place in different sections of the monolith in a short contact time syngas reactor. The monolith comprises an active catalyst material supported by a multi-layer structure made of thin, porous metal pieces, the opposing faces of which are joined together at their perimeters. The metal pieces may be perforated disks made of at least two metals or metal oxides, and may also include a metal oxide coating.
