Catalysts for SPOC(TM) enhanced synthesis gas production

摘要

A process and system for producing synthesis gas by a SPOC(R) enhanced catalytic partial oxidation process is disclosed. Light hydrocarbons in a H₂S-containing feed gas are partially oxidized to produce hydrogen and carbon monoxide over a catalyst that simultaneously oxidizes the H₂S to produce elemental sulfur. A reaction in which H₂S is partially oxidized to elemental sulfur and water takes place instead of a secondary reaction in which a portion of the light hydrocarbon feed is combusted to form CO₂ and water. An increase in yield and selectivity for CO and H₂ products results, and readily recoverable elemental sulfur is also produced.
