1. A process for the preparation of carbon monoxide and hydrogen from a hydrocarbonaceous feedstock, which process comprises contacting a mixture of the feedstock and an oxygen-containing gas with a catalyst comprising a catalytically active metal, selected from the group consisting of Ru, Rh, Os and Ir, associated with a metal cation selected from the group consisting of Al, Mg, Zr, Ti, La, Hf, and Si supported on a carrier, said catalyst prepared by a process comprising: providing the metal cation and the catalytically active metal in solutions adapted for impregnation or co-impregnation on the carrier; drying; and, optionally calcining; wherein the mixture is contacted with the catalyst at a temperature of at least about 750° C., at a pressure of up to about 150 bara, and at a gas hourly space velocity in the range of from about 20,000 Nl/kg/h to about 100,000,000 Nl/kg/h. 2.
