A process for the partial oxidation of hydrocarbons, such as methane, to produce hydrogen and carbon monoxide is provided. The process is conducted by contacting a mixture of a hydrocarbon-containing gas and an oxygen-containing gas in the presence of a metal catalyst at high gas velocities and low reaction initiation temperatures. The metal catalyst is a transition metal selected from the group of nickel, cobalt, iron, platinum, palladium, iridium, rhenium, ruthenium, rhodium, osmium and combinations thereof supported on a ceria monolith. Less than 3% by volume of carbon dioxide is present in the product gas.

1. A process for the partial oxidation of hydrocarbons to produce hydrogen and carbon monoxide and less than 3% carbon dioxide, the process comprising contacting a mixture of a hydrocarbon containing feed gas and an oxygen containing feed gas with a catalytically effective amount of a reduced metal catalyst consisting essentially of a metal selected from the group of nickel, cobalt, iron, platinum, palladium, iridium, rhenium, ruthenium, rhodium, osmium and combinations thereof supported on or in a ceria monolith support at a pressure of between 1 and 20 atmospheres, a feed gas standard gas hourly space velocity of about 50,000 to about 500,000 hr-1, and a linear velocity of about 0.5 to 5.0 ft/s, wherein said partial oxidation has an initiation temperature of below 200.degree.
