The invention provides a process for removing COS and HS from a feed synthesis gas stream comprising COS and HS, the process comprising contacting the feed synthesis gas stream with solid adsorbent at a temperature in the range of from 100 to 240&#xb0; C. to remove carbonyl sulphide and hydrogen sulphide, thereby obtaining a purified synthesis gas stream, wherein the solid adsorbent comprises one or more metals or oxides of the metals or combinations thereof and the metals are selected from the group of Ag, Sn, Mo, Fe and Zn.

Process for removing carbonyl sulphide and hydrogen sulphide from a synthesis gas stream

A process for the reduction of carbonyl sulfide (COS) in a gas stream is described. It comprises contacting the gas stream with an iron oxide-based material. The present invention relates to the removal of COS from any type of gas stream, in particular those which include one or more of the group comprising ethane, methane, hydrogen, carbon dioxide, hydrogen cyanide, ammonia, hydrogen sulfide, and noble gases. These include natural gas, and in particular syngas. Syngas is useable in a Fischer-Tropsch process. The present invention provides a simple but effective process for the reduction of COS, especially with a material that can easily be located in existing guard beds&#x2014;avoiding any re-engineering time and costs. The iron oxide-based materials can also be useable against other impurities, providing a single bed solution.
