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.
