PROCESS TO PREPARE A MIXTURE OF CARBON MONOXIDE AND HYDROGEN

摘要

Process to prepare a mixture of hydrogen and carbon monoxide from a gaseous mixture of hydrocarbons comprising methane, ethane and optional higher carbon number hydrocarbons (3) by performing the following steps: (a) pre-reforming (4) the hydrocarbon mixture in the presence of a suitable reforming catalyst to convert ethane, and the optional higher carbon number hydrocarbons to methane, carbon dioxide and hydrogen, (b) heating (6) the gaseous mixture obtained in step (a) to a temperature greater than 650 °C, (c) performing a partial oxidation (11) by contacting the heated mixture of step (b) with a source of oxygen (9) in a reactor burner yielding a reactor effluent (12).
