摘要： This disclosure relates to supported multi-metallic catalysts for use in the hydrotreating of hydrocarbon feeds, as well as a method for preparing such catalysts. The catalysts are prepared from a catalyst precursor comprised of at least one Group VIB metal, at least one Group VIII metal and an organic acid. The catalyst precursor is thermally treated to partially decompose the organic acid, then sulfided. The catalysts have a high carbon-as-carboxyl to total carbon ratio (Ccarboxy/Ctotal) as a result of a unique post-metal calcination method employed during the manufacture of the catalyst. As a result, the hydrotreating catalysts have lower percent weight loss-on-ignition, higher activity and longer catalyst life.

摘要： Spheroidal catalyst support, supported catalyst, and method of preparing and using the catalyst for hydrodemetallation of metal-containing heavy oil feedstocks are disclosed. The catalyst supports comprise titania alumina having 5 wt % or less titania and have greater than 30% percent of their pore volume in pores having a diameter of between 200 and 500 Å. Catalysts prepared from the supports contain Group 6, 9 and 10 metals or metal compounds supported on the titania alumina supports. Catalysts in accordance with the invention exhibit improved catalytic activity and stability to remove metals from heavy feedstocks during a hydrotreating process. The catalysts also provide increased sulfur and MCR conversion during a hydrotreating process.

摘要： 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.
