  • Hollow microsphere catalyst support and methods of making same
    Patent number: 9358533
    Abstract: Hollow porous metal oxide microspheres are provided. The microspheres may be used as a support for a catalyst, particularly an exhaust treatment catalyst for an internal combustion engine. Also provided are methods of making the microspheres, methods of using the microspheres as catalyst supports, and methods of exhaust treatment using catalyst articles comprising the microspheres.
    Type: Grant

  • Alumina-Based Perovskite Catalysts and Catalyst Supports
    Publication number: 20100227758
    Abstract: An alumina-based perovskite is formed by mixing a lanthanide source with a transitional alumina to form a dual-phase composition comprising in situ formed LnAlO3 dispersed in alumina. A second metal can be also included to form LaMO3 perovskite on alumina. The lanthanide content of the composition may range from about 6 to 35 wt. %, and the second metal from about 0.5 to 20 wt. %, to yield a high surface area composition which is useful as a catalyst or catalyst support such as for precious metals.

  • Alumina-Based Perovskite Catalysts and Catalyst Supports
    Publication number: 20090208396
    Abstract: An alumina-based perovskite is formed by mixing a lanthanide source with a transitional alumina to form a dual-phase composition comprising in situ formed LnAlO3 dispersed in alumina. The lanthanide content of the composition ranges from about 12 to 24 wt. % to yield a high surface area composition which is useful as a catalyst or catalyst support such as for precious metals.
