Abstract
Process for the production of synthesis gas, by means of catalytic partial oxidation or autothermal reforming of light hydrocarbons, which comprises partially oxidizing the hydrocarbon with oxygen coming from the reduction of at least one metal oxide selected from hexavalent chromium oxide, supported on an inert carrier and modified with an alkaline and/or earth-alkaline metal, and metal oxides capable of autonomously sustaining the catalytic partial oxidation reaction by means of redox cycles.
Claims15
A process for the production of synthesis gas, which comprises:
- partially oxidizing or autothermally reforming a light hydrocarbon gas with a solid comprising hexavalent chromium oxide, supported on an inert carrier and modified with an alkali or alkaline earth metal, and metal oxides that are capable of autonomously sustaining the catalytic partial oxidation reaction by means of redox cycles, wherein the light hydrocarbon contacts the chromium oxide and extracts oxygen therefrom thereby partially reducing said hexavalent chromium oxide.
A process for the production of synthesis gas, which comprises:
- feeding a hydrocarbon stream into a reactor in which a light hydrocarbon gas solely is partially oxidized or autothermally reformed to a synthesis gas in the presence of hexavalent chromium oxide supported on an inert carrier and modified with an alkali or, alkaline earth metal, and metal oxides that are capable of autonomously sustaining the catalytic partial oxidation reaction by means of redox cycles, the hexavalent chromium oxide functioning as a source of oxygen for the oxidation of the light hydrocarbon gas and thereby being partially reduced.
