    • The present invention pertains to a process for sulfiding a catalyst composition comprising at least one hydrogenation metal component of Group VI and/or Group VIII of the Periodic Table, and an organic additive wherein the catalyst composition is first contacted with an organic liquid, followed by the catalyst being contacted with hydrogen and a sulfur-containing compound in the gaseous phase, wherein less than about 40%, preferably less than about 35%, more preferably less than about 25%, most preferably less than about 15%, of the sulfur present in the sulfided catalyst is added with the organic liquid. The process of the present invention makes it possible to use additive-containing catalysts without loss of activity in units which cannot effect gas phase start-up or are required to carry out a pressure test. The organic liquid may be a hydrocarbon with a boiling range of about 150-500° C., preferably gasoline, white spirit, diesel, gas oil, mineral lube oil, or white oil. The step of contacting the catalyst with hydrogen and a sulfur-containing compound may take place in one step at a temperature of about 150-450° C. It may also take place in two steps, with the first step being performed at a temperature which is lower than that of the second step, with the first step being carried out at a temperature of about 100-250° C. and the second step at a temperature of about 150-450° C.
    • 本发明涉及一种硫化催化剂组合物的方法,该催化剂组合物包含至少一种元素周期表第VI族和/或第Ⅷ族氢化金属组分和一种有机添加剂,其中催化剂组合物首先与有机液体接触, 催化剂在气相中与氢气和含硫化合物接触,其中少于约40%,优选小于约35%,更优选小于约25%,最优选小于约15%的硫 存在于硫化催化剂中的有机液体中加入。 本发明的方法使得可以在不能实现气相启动或需要进行压力试验的单位中使用不含活性的添加剂的催化剂。 有机液体可以是沸点为约150-500℃的烃,优选汽油,白酒,柴油,瓦斯油,矿物润滑油或白油。 使催化剂与氢气和含硫化合物接触的步骤可以在约150-450℃的温度下在一个步骤中进行。它也可以在两个步骤中进行,第一步是在 低于第二步骤,第一步骤在约100-250℃的温度下进行,第二步在约150-450℃的温度下进行。

    • The invention pertains to a process for reducing the sulphur content of a hydrocarbon feedstock to a value of less than 500 ppm, which process comprises contacting a feedstock with a 95% boiling point of 450° C. or less and a sulphur content of 0.1 wt. % or more in the presence of hydrogen under conditions of elevated temperature and pressure with a first catalyst comprising a Group VI hydrogenation metal component and a Group VIII hydrogenation metal component on an oxidic carrier, after which at least part of the effluent from the first catalyst is led to a second catalyst comprising a Group VI hydrogenation metal component and a Group VIII hydrogenation metal component on an oxidic carrier which comprises 1 to 15 wt. % of silica, calculated on the weight of the catalyst. The use of a silica-containing catalyst in the second bed shows an improvement over the use of a second catalyst with an alumina carrier in the production of products with a sulphur content of less than 500 ppm, preferably less than 350 ppm. An improvement in hydrodenitrogenation activity is also obtained.
    • 本发明涉及一种将烃原料的硫含量降低到小于500ppm的方法,该方法包括使原料与95℃沸点450℃或更低,硫含量为0.1wt 。 在高温和高压条件下,在含有第VI族氢化金属组分和第Ⅷ族加氢金属组分的第一催化剂的氧化载体上,在氢气存在下,还可以含有至少一部分来自第一催化剂 被引入到包含1至15重量%的氧化载体上的第VI族氢化金属组分和第VIII族氢化金属组分的第二种催化剂。 二氧化硅的百分比以催化剂的重量计算。在第二床中使用含二氧化硅的催化剂显示出在使用具有氧化铝载体的第二催化剂用于生产硫含量小于 500ppm,优选小于350ppm。 也可获得加氢脱氮活性的改善。
