    • A process for desulphurising and dewaxing a hydrocarbon feedstock boiling in the gasoil boiling range to obtain a desulphurised and dewaxed gasoil fraction for use in an ultra low sulphur diesel fuel, comprising the following steps: (a) hydrodesulphurising the hydrocarbon feedstock boiling in the gasoil boiling range by contacting the feedstock in a hydrodesulphurisation reaction zone at elevated temperature and pressure, in the presence of hydrogen, with a hydrodesulphurisation catalyst and withdrawing a liquid hydrodesulphurisation effluent from the reaction zone; (b) catalytically dewaxing the liquid hydrodesulphurisation effluent to obtain a desulphurised and dewaxed gasoil fraction by contacting the liquid hydrodesulphurisation effluent, at elevated temperature and pressure in the presence of hydrogen, with a stacked bed of catalysts having a first upstream bed of noble metal containing hydrofinishing catalyst and a second downstream bed of noble metal containing dewaxing catalyst, wherein hydrogen and the liquid effluent are countercurrently supplied to the stacked bed of catalysts.
    • 一种用于在油烟沸点范围内沸腾的烃原料脱硫和脱蜡以获得用于超低硫柴油燃料的脱硫和脱蜡汽油部分的方法,包括以下步骤:(a)将在沸石沸腾沸腾的烃原料加氢脱硫 通过在加氢脱硫反应区中在升高的温度和压力下,在氢的存在下与加氢脱硫催化剂接触原料并从反应区抽出液体加氢脱硫流出物; (b)将液体加氢脱硫流出物进行催化脱蜡以获得脱硫和脱蜡的汽油部分,通过在氢存在下,在高温和高压下使液体加氢脱硫流出物与具有第一上游贵金属上游床的层叠床接触, 加氢精制催化剂和含贵金属的脱蜡催化剂的第二下游床,其中氢气和液体流出物逆流供应到催化剂层叠床。
