  • Catalysts for heterogeneously catalyzed reactions
    Publication number: 20020007097
    Abstract: Catalysts for heterogeneously catalyzed reactions which comprise active components and a catalyst support comprising amounts of &dgr;-Al2O3 which can be detected by X-ray diffractometry, in particular for the oxychlorination of ethylene to 1,2-dichloroethane.
    Type: Application
    Filed: May 3, 2001
    Publication date: January 17, 2002
    Inventors: Christian Walsdorff, Ruprecht MeiBner, Klaus Harth
  • Shaped catalysts
    Publication number: 20010029235
    Abstract: Shaped catalysts for heterogeneously catalyzed reactions are in the form of hollow cylinders or annular tablets whose end faces are rounded both to the outer edge and to the edge of the central hole, i.e. have no right-angled edges.
    Type: Application

  • Preparation of 1,2-dichloroethane
    Publication number: 20010011149
    Abstract: A process for the preparation of 1,2-dichloroethane by oxychlorination of ethene in the presence of a copper-containing fixed-bed catalyst comprising a bed essentially consisting of catalyst particles which comprise, at least partially, support material impregnated with an active component and, if desired, a promoter, where the catalyst bed comprises essentially no separate inert material for dilution.
