    • A process for removal of acetylenic compounds from hydrocarbon streams in which a hydrocarbon feed having a target fraction which contains a first concentration of acetylenic compounds and olefins is contacted with a catalyst selective for the hydrogenation of acetylenic compounds in the presence of hydrogen and a solvent having a boiling point higher than the boiling of the target fraction in a distillation reaction zone under conditions of temperature, pressure and hydrogen concentration favoring the hydrogenation of acetylenic compounds in which the target fraction is recovered as overheads having a second concentration of acetylenic compounds lower than said first concentration and the solvent is recovered as bottoms.
    • 一种从烃流中除去炔属化合物的方法,其中具有含有第一浓度的炔属化合物和烯烃的目标馏分的烃进料在氢气和溶剂存在下与选择性氢化炔属化合物的催化剂接触, 在温度,压力和氢气浓度的条件下,沸点高于蒸馏反应区中沸点的沸点,有利于炔属化合物的氢化反应,其中目标级分被回收,其中第二浓度的炔属化合物的二级浓度低于所述 第一浓度,溶剂作为底部回收。

    • 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。
