A HIGH ACTIVITY HYDRODESULFURIZATION CATALYST, A METHOD OF MAKING SAID CATALYST, AND A PROCESS FOR MANUFACTURING AN ULTRA-LOW SULFUR MIDDLE DISTILLATE FUEL |
摘要 |
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 ~F(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. |
