Improved supported hydroprocessing catalysts, and their method of preparation useful for the hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) of a petroleum feedstock, including a residuum hydrocarbon feedstock are disclosed. The Catalysts contain at least one Groups VIB metal component, at least one Group VIII metal component, and a phosphorus component, supported on a foraminous support such as alumina. The supported catalysts are characterized by a specific combination of properties, namely, the Group VIII metal to Phosphorous molar ratio, the Group VIII metal to Group VIB metal molar ratio, the phosphorous component to Group VIB component molar ratio and the median pore diameter. The resulting catalysts exhibit enhanced HDN without sacrificing to any significant degree the HDS activity.
A supported catalyst comprising at least one metal containing catalyst component and at least one phosphorous containing catalyst component, wherein the metal in the metal containing catalyst component is least one selected from Group VIB of the Periodic Table of the Elements, at least one other one metal selected from Group VIII of the Periodic Table of the Elements, and wherein said catalyst components are carried on a foraminous support, said catalyst being characterized as having:
A method for preparing a supported catalyst having a high hydrodenitrogenation (HDN) selectivity during hydroprocessing of a feedstock, which method comprises impregnating a foraminous support with an aqueous solution containing at least one metal containing catalyst component and at least one phosphorous containing catalyst component, wherein the metal in the metal containing catalyst component is least one selected from Group VIB of the Periodic Table of the Elements, at least one other metal in the metal containing catalyst component is selected from Group VIII of the Periodic Table of the Elements, said components being thermally decomposable to the metal oxides, and thereafter drying and calcining the resulting impregnated support to provide a supported catalyst, said supported catalyst being characterized as having:
A supported catalyst comprising at least one metal containing catalyst component and at least one phosphorous containing catalyst component, wherein at least one metal in the metal containing catalyst component is a Group VIB metal of the Periodic Table of the Elements selected from chromium, tungsten and molybdenum, and at least one other metal in the metal containing catalyst component is a Group VIII metal Periodic Table of the Elements selected from cobalt, and nickel, and wherein said catalyst components are carried on a foraminous support, said catalyst being characterized as having:
