Disclosed is method for removing carbonyl sulphide and/or carbon disulphide from a sour gas stream. The method comprises subjecting the gas stream to simultaneous contact with an absorption liquid, such as an aqueous amine solution, and with a catalyst suitable for hydrolyzing carbonyl sulphide and/or carbon disulphide. To this end, the invention also provides a reactor system wherein both an absorption liquid and a catalyst are present. In a preferred embodiment, the catalyst is a heterogeneous catalyst present on or in an absorption column, either coated on the trays of a column with trays, or contained in the packing of a packed column.
A reactor system for removing carbonyl sulphide (COS) and/or carbon disulphide (CS2) from a sour gas stream, wherein the reactor system comprises an absorption column, wherein the absorption column contains an absorption liquid and comprises a catalyst suitable for hydrolyzing COS and CS2, wherein the catalyst is a transition metal or a salt of a transition metal, and wherein the catalyst is present in or on the absorption column.
