  • Catalysts, methods of making catalysts, and methods of combustion
    Patent number: 7981831
    Abstract: Catalysts are described in which an active catalyst is disposed on a low surface area, oxide support. Methods of forming catalysts are described in which a Cr-containing metal is oxidized to form a chromium oxide layer and an active catalyst is applied directly on the chromium oxide layer. Methods of making new catalysts are described in which the surface is sonicated prior to depositing the catalyst. Catalyst systems and methods of oxidation are also described. The inventive systems, catalysts and methods are, in some instances, characterized by surprisingly superior results.
    Type: Grant
    Filed: December 18, 2007
    Date of Patent: July 19, 2011
    Assignee: Velocys
    Inventors: Barry Lee-Mean Yang, Ruiqiang Long, Junko M. Watson, Abhishek Gupta

  • Superior pillared clay catalysts for selective catalytic reduction of nitrogen oxides for power plant emission control
    Patent number: 6521559
    Abstract: The present invention provides a catalyst for selective catalytic reduction of nitrogen oxide compounds with ammonia comprising a composition of one or more pillared interlayered clays, one or more metal ions exchanged with the pillared interlayered clays, and one or more promoter ions exchanged with the pillared interlayered clays. Specifically, the pillared interlayered clay (PILC) catalysts of the present invention include Fe3+, Cr3+, Mn2+, Co2+, Cu2+, and Ni2+ exchanged Al2O3-PILC, TiO2-PILC, ZrO2-PILC or SiO2-PILC catalysts. The promoters include Ce, La, Pr, Th and Nd. These pillared clay catalysts of the present invention show remarkable activity for the SCR reaction.
