A method for producing a sulphided copper sorbent includes the steps of: (i) contacting a sorbent precursor material containing one or more sulphidable copper compounds, with a sulphiding gas stream including hydrogen sulphide to form a sulphided sulphur-containing sorbent material, and (ii) subjecting the sulphided sulphur-containing sorbent material to a heating step in which it is heated to a temperature above that used in the sulphiding step and ≧110° C., under an inert gas selected from nitrogen, argon, helium, carbon dioxide, methane, and mixtures thereof, the inert gas optionally including hydrogen sulphide. The method provides sulphided copper sorbents that have reduced levels of elemental sulphur. |
