| 摘要 |
A process for desulphurising hydrocarbons is described 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 mixture over a further desulphurisation material, wherein the further desulphurisation material comprises one or more nickel compounds, a zinc oxide support material, and optionally one or more promoter metal compounds selected from compounds of iron, cobalt, copper and precious metals, said desulphurisation material having a nickel content in the range 0.3 to 20 % by weight and a promoter metal content in the range 0 to 10% by weight. |
