Publication number: 20090025375Abstract: The inventions relates to catalysts comprising precious metals supported on La stabilized refractory metal oxides. The La is provided on the surface of the refractory metal oxide in an amount to form at least about a monolayer, preferably about 1-2 mono-layers. Preferably, the La has no crystalline structure shown by X-ray diffraction. Nd and mixtures of La and Nd can be used in place of La. In one embodiment, the catalyst is a reforming catalyst comprising an effective amount of Rh on a ZrO2 support. Preferably, the Rh is provided in a relatively low concentration, typically about 0.5% or less based on the weight of the ZrO2 support. The inventors have found that if the Rh loading is kept sufficiently low, the Rh can be maintained in the form of small particles (less than 5 nm, typically about 2 nm or less) through lean rich cycling as a consequence of an effect involving the La.Type: ApplicationFiled: July 26, 2007Publication date: January 29, 2009Applicant: Eaton CorporationInventors: Damodara M.

Patent number: 6933409Abstract: Noble metal/reducible metal oxide catalysts effective for the direct amination of aromatic hydrocarbons and heterocyclic analogs thereof are disclosed. In one embodiment, the cataloxidant comprises a noble metal selected from Pd, Rh, Ir and/or Ru and a reducible metal oxide. In another embodiment, the cataloxidant comprises a noble metal and a reducible oxide of a metal selected from Ni, Mn, V, Ce, Th, Pr, Te, Re, Co, Fe, Cu and/or Bi. A preferred cataloxidant comprises one or more noble metals selected from Pd, Rh, Ir and/or Ru, in combination with nickel oxide and/or manganese oxide. In preferred applications, benzene can be aminated in the presence of the cataloxidants to form aniline. A benzene conversion of at least 5% is achieved, with more than 90% selectivity for aniline. Significantly, the cataloxidant can be regenerated without a substantial loss of performance.Type: GrantFiled: May 15, 2000Date of Patent: August 23, 2005Assignees: Symyx Technologies, Inc., Bayer AGInventors: Damodara M.
