  • Catalysts with high cobalt surface area
    Patent number: 7501378
    Abstract: A method of making a cobalt-containing catalyst precursor, comprising slurrying a transition alumina powder with an aqueous solution of a cobalt ammine complex, heating the slurry to cause the cobalt ammine complex to decompose with the deposition of an insoluble cobalt compound, filtering the solid residue from the aqueous medium, and drying the solid residue.
    Type: Grant
    Filed: March 18, 2008
    Date of Patent: March 10, 2009
    Assignee: Johnson Matthey PLC
    Inventors: Martinus C. Lok, Gordon J. Kelly, Gavin Gray

  • Catalysts with high cobalt surface area
    Patent number: 7368625
    Abstract: A catalyst or precursor thereto comprising cobalt and/or a cobalt compound on a transition alumina support having a total cobalt content of at least 41% by weight and a cobalt surface area, after reduction, greater than 25 m2 per gram of total cobalt. The catalyst or precursor may be made by slurrying a transition alumina powder having a pore volume of at least 0.7 ml/g with an aqueous cobalt ammine carbonate complex and heating the slurry to decompose the complex.

  • Aldol condensation reaction and catalyst therefor
    Patent number: 6706928
    Abstract: Production of unsaturated ketones by the aldol condensation of ketones such as acetone or methyl ethyl ketone by contacting the ketone in the vapor phase with a particulate catalyst comprising at least one basic alkali metal compound supported on an inert substrate at a temperature above 175° C. The produce ketones may be hydrogenated to form saturated ketones or alcohols.
