<p>Catalysts and processes for the catalytic conversion of hydrocarbons to carbon monoxide and hydrogen employing new families of chromium-rare earth based catalysts are disclosed. One highly active and selective catalyst system, providing greater than 95 % CH4 conversion, and 97-98 % selectivity to CO and H2 by a net catalytic partial oxidation reaction, is a Ce-Cr-Ni containing compound. A preferred process for the catalytic conversion of a hydrocarbon comprises contacting a feed stream comprising a methane-containing hydrocarbon feedstock and an oxygen-containing gas with a chromium-rare earth containing catalyst in a short contact time reactor maintained at partial oxidation promoting conditions effective to produce synthesis gas.</p> |
