DESULPHURISATION MATERIAL, METHOD OF MAKING SAME AND DESULPHURISATION PROCESS USING SAME

摘要

A particulate desulphurisation material is described comprising one or more nickel compounds, one or more copper compounds, a zinc oxide support material, and one or more alkali metal compounds wherein the nickel content of the material is in the range 0.3 to 10% by weight, the copper content of the material is in the range 0.3 to 10% by weight and the alkali metal content of the material is in the range 0.2 to 10% by weight. A method of making the desulphurisation material is also described comprising the steps: (i) contacting a nickel compound and copper compound with a particulate zinc support material and an alkali metal compound to form an alkali-doped composition, (ii) shaping the alkali-doped composition, and (iii) drying. The desulphurisation material may be used to desulphurise hydrocarbon gas streams with reduced levels of hydrocarbon hydrogenolysis.
