  • Publication number: 20110301398
    Abstract: Olefins are oligomerized by bringing at least one C2 to C8-olefin into contact with a nickel-containing heterogeneous catalyst. The catalyst is conditioned before contact with the olefin by passing an inert gas flow over the same, until the inert gas flow has a water content of less than 1000 ppm. Selectivity for the production of higher oligomers, in particular trimers relative to the formation of dimers is increased by the pretreatment.

  • Patent number: 7868111
    Abstract: The present invention provides a method for producing ?-olefin polymer, comprising polymerizing ?-olefins in the presence of a halogen atom-containing acid catalyst by use of an aliphatic hydrocarbon having 3-12 carbon atoms, which contains 5 to 95 mass % of ?-olefin, as a raw material; removing catalyst residue and halogen-containing compounds by bringing a product in the polymerization step into contact with an aluminum atom-containing inorganic solid treatment agent with or without deactivating the catalyst; and separating the ?-olefin polymer. According to this method, the catalyst residue and other halogen-containing compounds can be removed, without relying on aqueous deactivation and separation steps using an alkaline aqueous solution or the like, from a polymerization reaction product obtained by polymerization in the presence of a halogen-containing acid catalyst by use of an ?-olefin-containing liquid hydrocarbon as a raw material.
