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.

Abstract: Process, reactor and burner for the gasification of a hydrocarbon fuel. The burner comprises coaxial channels for the separate supply of an oxidizer gas, a hydrocarbon fuel and a moderator gas. A coaxial channel with the smallest width is bordered by a separating wall with at least one gas exchange. The gas exchange passage can for example be formed by a retracted end of the separating wall and/or by openings in the separating wall.

Abstract: The present invention relates to a process for converting feed streams selected from (1) a gas stream comprising carbon dioxide and a hydrogen rich gas stream; (2) a methane rich gas stream; and (3) a combination of feed streams (1) and (2) into a product stream comprising carbon monoxide, water and hydrogen. The process may include introducing feed streams selected from (1), (2) or (3) and oxygen into a reaction vessel and switching modes between performing method I or method II in the reaction vessel wherein no catalyst is present. The reaction vessel may be provided with a burner located at the top of the reaction vessel, the burner may include coaxial channels for the separate introduction of the different gas streams. Method I may be a reverse water gas shift reaction at elevated temperature. Method II may be a partial oxidation reaction at elevated temperature.
