    • A method of making a high activity catalyst composition suitable for use in the hydrodesulfurization of a middle distillate feed, such as diesel fuel, having a high concentration of sulfur, to thereby provide a low sulfur middle distillate product. The method comprises heat treating aluminum hydroxide under controlled temperature conditions thereby converting said aluminum hydroxide to gamma-alumina to give a converted aluminum hydroxide, and controlling the fraction of said converted aluminum hydroxide that is gamma-alumina by controlling said controlled temperature conditions to within a calcination temperature range of from 850° F. (454° C.) to 950° C. (510° C.) so that essentially all of said aluminum hydroxide is converted to a transition alumina but less than a material amount of the converted aluminum hydroxide is converted to a transition alumina other than gamma-alumina. A catalytic component is incorporated into said converted aluminum hydroxide to provide an intermediate, which is heat treated to provide said high activity catalyst composition. The high activity catalyst composition can, thus, comprises gamma-alumina and a catalytic component, but having a material absence of aluminum hydroxide and a phase of a transition alumina other than gamma-alumina. Another embodiment of the high activity catalyst composition comprises a support material consisting essentially of gamma-alumina and a catalytic component. The high activity catalyst composition can suitably be used in the hydrodesulfurization of a middle distillate feed containing a high sulfur concentration.
    • 制备高活性催化剂组合物的方法,该组合物适用于具有高浓度硫的中等馏出物(例如柴油)的加氢脱硫,从而提供低硫中间馏分产物。 该方法包括在受控温度条件下热处理氢氧化铝,从而将所述氢氧化铝转化为γ-氧化铝,得到转化的氢氧化铝,并通过将所述受控温度条件控制在一个 煅烧温度范围为850°F(454℃)至950℃(510℃),使得基本上所有的所述氢氧化铝转化为过渡氧化铝,但小于转化的铝的材料量 将氢氧化物转化为除γ-氧化铝之外的过渡氧化铝。 将催化组分并入所述转化的氢氧化铝中以提供中间体,其被热处理以提供所述高活性催化剂组合物。 因此,高活性催化剂组合物可以包含γ-氧化铝和催化组分,但是其材料不存在氢氧化铝和除γ-氧化铝之外的过渡氧化铝的相。 高活性催化剂组合物的另一个实施方案包括基本上由γ-氧化铝和催化组分组成的载体材料。 高活性催化剂组合物可适用于含有高硫浓度的中间馏分进料的加氢脱硫。
