Patent number: 7201838Abstract: Fischer-Tropsch hydrocarbon synthesis using a cobalt catalyst is used to produce waxy fuel and lubricant oil hydrocarbons from synthesis gas derived from natural gas. The waxy hydrocarbons are hydrodewaxed, with reduced conversion to lower boiling hydrocarbons, by contacting the waxy hydrocarbons, in the presence of hydrogen, with an unsulfided 10-ring, 1-dimensional zeolite catalyst that has been reduced and then treated by contacting it with the synthesized hydrocarbons containing one or more oxygenates, including indigenous oxygenate. Tail gas from the hydrodewaxing reactor can be used for the hydrocarbon synthesis.Type: GrantFiled: August 29, 2003Date of Patent: April 10, 2007Assignee: ExxonMobil Research and Engineering CompanyInventors: Adeana Richelle Bishop, William Berlin Genetti, Jack Wayne Johnson, Loren Leon Ansell, Nancy Marie Page

Patent number: 7201839Abstract: A composition comprising a metal oxide, a silica-containing material, a gallium-containing material, an aluminum-containing material, and a promoter, wherein at least a portion of the promoter is present as a reduced-valence promoter and methods of preparing such composition are disclosed. The thus-obtained composition is employed in a desulfurization zone to remove sulfur from a hydrocarbon stream.Type: GrantFiled: December 12, 2003Date of Patent: April 10, 2007Assignee: ConocoPhillips CompanyInventors: Uday T. Turaga, Jason J. Gislason
