  • Alkali metal catalytic slurry composition
    Patent number: 5126306
    Abstract: A catalyst system composition and a dimerization process utilizing said catalyst system composition are disclosed. The catalyst system composition comprises at least one elemental alkali metal combined with at least one particulate solid, and optionally a promoter, to form a slurry. This catalyst system is contacted with at least one olefin in order to produce a dimerized product.

  • Product and process of hydrogen treatment of olefin dimerization catalysts
    Patent number: 5081093
    Abstract: Catalyst supports, catalyst systems, methods for the preparation thereof, in dimerization processes therewith are provided. Catalyst supports are prepared from extruding alkali metal carbonate and a liquid. Optionally, the extruded catalyst support further comprises a carbonaceous compound. Catalyst systems comprise at least one elemental alkali metal deposited on the extruded catalyst support. Optionally, the catalyst system further comprises of at least one promoter. A hydrided catalyst system is prepared by contacting the catalyst system with hydrogen to reduce the dimerization induction period.
