Abstract: The invention provides a process for the removal of COS and H2S from a synthesis gas stream comprising COS and H2S, the process having the steps of: removing H2S from a feed synthesis gas stream with a first solid adsorbent to obtain a first synthesis gas stream, converting COS in the first synthesis gas stream to H2S by contacting the first synthesis gas stream with a COS-hydrolysing catalyst in the presence of water in a hydrolysis zone to obtain a second synthesis gas stream depleted of COS and enriched in H2S; and removing H2S from the second synthesis gas stream by contacting the second synthesis gas stream with a second solid adsorbent in a H2S removal zone to obtain a third synthesis gas stream depleted of H2S and depleted of COS to very low levels.

Abstract: 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—avoiding any re-engineering time and costs. The iron oxide-based materials can also be useable against other impurities, providing a single bed solution.
