A process to prepare a mixture of hydrogen and carbon monoxide from a methane containing gaseous feed by performing the following steps, (a) performing a partial oxidation by contacting the feed with an oxygen containing gas to prepare a gaseous mixture comprising hydrogen, carbon monoxide, steam, carbon dioxide, methane and soot particles said mixture having an elevated temperature, (b) passing the gaseous mixture of step (a) through a filter where the soot particles are retained on the filter and a mixture comprising hydrogen, carbon monoxide, carbon dioxide, methane poor in soot is obtained wherein the filter is a ceramic foam filter or a ceramic wall-flow filter, and (c) converting the retained soot particles at the elevated temperature to carbon oxide.
