  • Catalyst support
    Patent number: 7148179
    Abstract: A catalyst support is produced by mixing particulate synthetic silica with 0.5–10 parts by weight of one or more particulate oxides or phosphates of the elements of group IIA, IIIB, IVB, VA, VIB, VIIB, VIII, IB, IIB, IIIA, IVA and lanthanides or precursors thereof, shaping the mixture and then calcining the shaped mixture to form the finished support. The formed support has improved stability relative to aging resistance under hydrothermal conditions. The catalyst support is used together with phosphoric acid in the production of alcohols from olefins by hydration. The resultant hydration catalysts have excellent activity and selectivity.
    Type: Grant
    Filed: May 9, 2005
    Date of Patent: December 12, 2006
    Assignee: Degussa AG

  • Catalyst support
    Publication number: 20050202962
    Abstract: A catalyst support consisting mainly of synthetic silica, with 0.5-10 parts by weight of one or more oxides or phosphates of the elements of group IIA, IIIB, IVB, VB, VIB, VIIB, VIII, IB, IIB, IIIA, IVA and the lanthanides characterised in that the support preparation method comprises mixing particulate synthetic silica with particulate oxides or phospates of the elements of Groups IIA, IIIB, IVB, VB, VIB, VIIB, VIII, IB, IIB, IIIA, IVA and the lanthanides, or with precursors thereof, a forming step and calcination. The catalyst support is used together with phosphoric acid in the production of alcohols from olefins by hydration.
