PROCESS TO PREPARE A SYNTHESIS GAS

摘要

Process to prepare a synthesis gas comprising hydrogen and carbon monoxide by performing a partial oxidation on a methane comprising feed (47) using a multi- orifice burner (17) provided with an arrangement of separate passages, wherein the gaseous methane comprising feed has a temperature above 5000C and flows through a passage of the burner, an oxidiser gas (18) flows through a separate passage of the burner and wherein the passage for gaseous hydrocarbon feed and the passage for oxidiser gas are separated by a passage through which a secondary gas flows, wherein the secondary gas comprises hydrogen, carbon monoxide and/or a hydrocarbon.
