Patent number: 4309278Abstract: A catalyst is provided which comprises a hydrogenation component and a support comprising agglomerates of alumina having initially not more than 0.20 cubic centimeters per gram of its pore volume in pores greater than about 400 Angstroms in diameter and a minor amount of silica. A process for the hydroconversion of hydrocarbonaceous oils utilizing the catalyst is also provided.Type: GrantFiled: November 24, 1980Date of Patent: January 5, 1982Assignee: Exxon Research & Engineering Co.Inventor: Willard H. Sawyer

Patent number: 4306965Abstract: 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.Type: GrantFiled: August 4, 1980Date of Patent: December 22, 1981Assignee: Standard Oil Company (Indiana)Inventors: Albert L. Hensley, Jr., Leonard M. Quick, Donald Hopkins
