<p>Combustion dispersed metal-metal oxide catalysts that are highly active for catalyzing the net partial oxidation of methane to CO and H2 are disclosed, along with their manner of making and processes for producing synthesis gas employing the new catalysts. A preferred catalyst comprises rhodium nanoparticles, with or without a rare earth promoter, that is deposited on α-alumina by combusting a mixture of catalyst precursor materials and a flammable organic compound. In a preferred syngas production process a stream of reactant gas mixture containing methane and O2 is passed over the catalyst in a short contact time reactor to efficiently produce a mixture of carbon monoxide and hydrogen at superatmospheric pressures.</p> |
