Patent number: 6989403Abstract: A process for regenerating a slurry Fischer-Tropsch catalyst, which needs regeneration, involves de-waxing and drying the catalyst sufficiently to produce a free-flowing catalyst powder that is fluidizable; fluidizing the catalyst powder; treating the catalyst powder with an oxygen treatment; reducing the catalyst powder with a reducing gas to form a reduced catalyst powder; and mixing the reduced catalyst powder with hydrocarbons to form a regenerated, slurry catalyst. The oxidation and reduction steps may be repeated. An oxygen treatment includes using a fixed O2 level with ramped temperatures, fixed temperatures with increased O2 levels, or a combination.Type: GrantFiled: April 23, 2004Date of Patent: January 24, 2006Assignee: Syntroleum CorporationInventors: Jui-Hsin R.

Patent number: 5366949Abstract: This invention is a catalyst and a process using that catalyst for oxidizing hydrogen bromide to form elemental bromine. The inventive catalyst composition comprises cerium bromide on certain zirconia containing supports. The zirconia support, preferably largely in the baddeleyite phase, stabilizes the cerium bromide catalyst against cerium oxide formation at operating temperatures and gives the catalyst excellent activity at lower temperatures.Type: GrantFiled: June 4, 1993Date of Patent: November 22, 1994Assignee: Catalytica, Inc.Inventor: Paul F. Schubert

Patent number: 5108975Abstract: Described is a method for preparing a catalyst support material, comprising commercially available silica, by utilizing a fluorine-containing acid. The novel method is utilized to produce a novel composition that has unique physical properties different from those of typical commercially available silica materials. The novel support material has significantly improved values for crush strength and as good or better pore volume than comparable catalyst support materials. Due to these improved physical properties, the novel composition is more durable and longer lived. Furthermore, the greater pore volume of the novel composition provides for enhanced catalytic activity when the formed silica material is utilized as a catalyst support.Type: GrantFiled: January 28, 1991Date of Patent: April 28, 1992Assignee: Phillips Petroleum CompanyInventors: Paul F.
