摘要： A process for hydrotreating a hydrocarbon stream such as petroleum distillate and similar hydrocarbon materials by contacting said stream with hydrogen and a catalyst comprising a porous refractory inorganic oxide support and deposited thereon hydrogenation components comprising chromium, molybdenum and at least one Group VIII metal. This process enables improved removal of nitrogen and sulfur, particularly from gas oils.

摘要： 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.

摘要： A method for reactivating the catalyst used in the mild hydrotreating of petroleum crude scale wax comprises contacting the catalyst with the feedstream at a temperature in excess of the normal operating temperature for the particular feedstream for a time sufficient to reactivate the catalyst and produce effluent having satisfactory color and stability characteristics. Operation at a temperature in excess of the normal operating temperature may follow conventional air-stream catalyst regeneration.
