Abstract

A process for preparing a syngas from a methane comprising gas includes reacting the methane comprising gas with an oxidising gas at an operating temperature in the range of 1150 to 1370° C. by means of non-catalytic partial oxidation. A hot raw syngas mixture having a methane content higher than the methane content in a state of thermodynamic equilibrium at the operating temperature applied is passed through a bed of methane oxidation catalyst for oxidising methane with steam formed in the non-catalytic POX into carbon monoxide and hydrogen. The methane oxidation catalyst has at least one catalytically active metal supported on a refractory oxide support material where soot particles present in the hot raw syngas mixture are retained. The retained soot particles are converted to carbon monoxide. Soot depleted syngas is recovered in a state of thermodynamic equilibrium.
