Abstract:
1. A process for desulphurising hydrocarbons comprising the steps of; (i) passing a mixture of hydrocarbon and hydrogen over a hydrodesulphurisation catalyst to convert organosulphur compounds present in said hydrocarbon to hydrogen sulphide, (ii) passing the resulting mixture over a hydrogen sulphide sorbent comprising zinc oxide to reduce the hydrogen sulphide content of the mixture, and (iii) passing the hydrogen sulphide-depleted gas mixture over a further desulphurisation material, wherein the further desulphurisation material comprises a shaped mixture of one or more particulate nickel compounds and a particulate zinc oxide support material, said desulphurisation material having a nickel content in the range 0.3 to 20% by weight, and wherein the particulate nickel compounds are neither impregnated on nor in the form of a co-precipitate with the particulate zinc oxide support material.
