Patent number: 6544439Abstract: Applicants have developed a novel catalyst composition comprising a crystalline metal oxide having the empirical formula: AvBt+wNixD(Gu−)yOz, where A is an alkali metal (e.g. Na), B is a basic metal (e.g. Ca), D is a framework component (e.g. P), and G is an anionic species (e.g. OH−). Nickel may be present in the framework of the crystalline metal oxide, dispersed thereon, or both. Preferably, the metal oxide component has an apatite or hydroxyapatite crystal structure. These crystalline metal oxide components have been found to have improved performance in partial oxidation and light hydrocarbon (e.g. methane) reforming to produce synthesis gas. A new process for synthesizing these metal oxides is also disclosed.Type: GrantFiled: December 22, 2000Date of Patent: April 8, 2003Assignee: UOP LLCInventors: Gregory J. Lewis, John E. Bauer

Patent number: 6503863Abstract: Disclosed is a method of heat treating a molecular sieve. The method comprises providing a template-containing molecular sieve, heating the molecular sieve under conditions effective to remove a portion of the template from the molecular sieve, and cooling the heated molecular sieve to leave an amount of template effective to cover catalytic sites within the molecular sieve. A catalyst composition is also provided which comprises a molecular sieve having a microporous structure and a binder, wherein between 10 and 90 vol % of the microporous structure is occupied by a material, the material comprising a template or a carbonaceous residue of a template, and the catalyst composition exhibits a Davison Index of not greater than 30.Type: GrantFiled: August 15, 2001Date of Patent: January 7, 2003Assignee: ExxonMobil Chemical Patents, Inc.Inventors: Shun C.

Patent number: 6432866Abstract: This invention relates to rigid porous carbon structures and to methods of making same. The rigid porous structures have a high surface area which are substantially free of micropores. Methods for improving the rigidity of the carbon structures include causing the nanofibers to form bonds or become glued with other nanofibers at the fiber intersections. The bonding can be induced by chemical modification of the surface of the nanofibers to promote bonding, by adding “gluing” agents and/or by pyrolyzing the nanofibeirs to cause fusion or bonding at the interconnect points.Type: GrantFiled: February 9, 2000Date of Patent: August 13, 2002Assignee: Hyperion Catalysis International, Inc.Inventors: Howard Tennent, David Moy, Chun-Ming Niu
