Abstract
Catalysts comprising a catalytically active metal on a NiO—MgO coated porous metal alloy support that are active for catalyzing the oxidative conversion of methane to CO and H2 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.
Claims11
A process for the catalytic partial oxidation of a hydrocarbon feedstock comprising:
- mixing together a hydrocarbon feedstock and an O2-containing gas to provide a reactant gas mixture;
- contacting a stream of said reactant gas mixture with a catalyst in a reaction zone maintained at catalytic partial oxidation-promoting conditions effective to produce an effluent stream comprising carbon monoxide and hydrogen, said catalyst comprising a mixture of nickel oxide and magnesium oxide supported on a metal substrate wherein said catalyst comprises a NiO—MgO layer about 690-4560 nm thick on said substrate and wherein said catalyst comprises a rhodium layer about 41-361 nm thick on said layer of nickel oxide and magnesium oxide.
