  • Supported catalysts and method for their production
    Patent number: 4450245
    Abstract: A catalyst support can be made by co-precipitating copper aluminate from a solution containing copper and aluminium ions and converting the precipitate into solid, generally particulate, form. The catalyst preferably includes a redox couple and may include promoters. The catalyst is of particular value for the low temperature oxidation of carbon monoxide, especially in a smoking product filter.
    Type: Grant
    Filed: March 25, 1982
    Date of Patent: May 22, 1984
    Assignee: Gallaher Limited

  • Smoking products
    Patent number: 4317460
    Abstract: Catalysts for the low temperature oxidation of carbon monoxide to carbon dioxide, used in smoking product filters, are described. The catalysts are carried upon a support which should be microporous. The catalysts may include mixtures of tin or tin compounds with other catalytic material. The catalysts may involve a Redox mechanism. The catalysts exhibit resistance to deactivation caused by contact with water.
    Type: Grant

  • Catalysts
    Patent number: 4256609
    Abstract: A catalyst is made by impregnating a highly microporous support with a solution of a substance providing catalytically active material in a mixture of water and an organic liquid that reduces the surface tension of the solution. The preferred solution contains 20 to 50% water and 50 to 80% methanol.

  • Catalysts
    Patent number: 4252687
    Abstract: A catalyst is made by creating a deficiency of hydroxyl groups in a hydroxyl containing support and contacting the support, while thus activated with a solution of a substance providing a catalytically active material. Generally the catalyst is made by contacting the solution with freshly crushed pellets of, for instance, a zeolite.
