Abstract
A process for desulphurizing hydrocarbons includes passing a mixture of hydrocarbon and hydrogen over a hydrodesulphurization catalyst to convert organosulphur compounds present in the hydrocarbon to hydrogen sulphide, passing the resulting mixture over a hydrogen sulphide sorbent including zinc oxide to reduce the hydrogen sulphide content of the mixture, and passing the hydrogen sulphide-depleted mixture over a further desulphurization material. The further desulphurization material includes one or more nickel compounds, a zinc oxide support material, and optionally one or more promoter metal compounds of iron, cobalt, copper and precious metals. The desulphurization material has a nickel content in the range 0.3 to 20% by weight and a promoter metal compound content in the range 0 to 10% by weight.
