  • Spherical particles
    Patent number: 7767772
    Abstract: Spherical particles comprising magnesium alcoholate and having a poured cone height of less than 17 mm are prepared by reacting magnesium, an alcohol or a mixture of various alcohols and a halogen and/or an optionally organic halogen compound with one another at below the boiling point of the alcohols. The spherical particles are employed as a precursor for olefin polymerization catalysts.
    Type: Grant
    Filed: November 3, 2004
    Date of Patent: August 3, 2010
    Assignee: Degussa AG
    Inventors: Michael Grün, Klaus Heyne, Claudine Mollenkopf, Sam Lee, Roger Uhrhammer

  • Method for the production of a titanium-containing zeolite
    Patent number: 6841144
    Abstract: The present invention concerns a method for the production of a titanium-containing zeolite whereby a synthesis gel is formed by combining and hydrolysing a hydrolysable silicon compound, a hydrolysable titanium compound and a basic quaternary ammonium compound in an aqueous medium, in quantities such that relative to the starting compounds the molar ratio of Si/Ti is greater than or equal to 30 and that of N/Si is 0.12 to less than 0.20, and the synthesis gel is then crystallised at a temperature of 150 ° C. to 220 ° C. for a period of less than 3 days, and a titanium-containing zeolite obtainable by this method.
