Abstract: A process for hydrotreating a hydrocarbon stream to remove nitrogen and sulfur which process comprises contacting a hydrocarbon stream comprising a stream selected from petroleum distillate, tar sands distillate, and shale oil, with hydrogen and a catalyst comprising a porous refractory inorganic oxide and deposited thereon hydrogenation components comprising chromium, molybdenum and at least one Group VIII metal, said catalyst having a pore volume distribution comprising 20-50% of pore volume in pores with diameters of 0-50 Angstrom units, 30-70% of pore volume in pores with diameters of 50-100 Angstrom units, 0-20% of pore volume in pores with diameters of 100-150 Angstrom units, and 0-10% of pore volume in pores with diameters greater than 150 Angstrom units.

Abstract: LARGE-PORE HYDRODEMETALLIZATION CATALYST AND PROCESS EMPLOYING SAME of the Invention There is disclosed a catalyst for the hydrodemetallization of petroleum hydrocarbon streams containing asphaltenes and large quantities of metals. This catalyst consists essentially of a small amount of a single hydrogenation metal selected from the group consisting of metals from Group VIB of the Periodic Table of Elements and metals from Group VIII of the Periodic Table deposed on a large-pore alumina. The hydrogenation metal may be present in the elemental form, as an oxide, as a sulfide, or mixtures thereof. The catalyst is characterized by a surface area of at least 120 square meters per gram, a pore volume of at least 0.7 cc per gram, and an average pore diameter of at least 125 Angstrom units. Suitable examples of a hydrogenation metal are nickel and molybdenum. Also disclosed is a process for the hydrodemetallization of a hydrocarbon stream containing asphaltenes and a substantial amount of metals, which process comprises contacting said hydrocarbon stream in a reaction zone under suitable operating conditions and in the presence of hydrogen with the catalyst described hereinabove.
