  • Patent number: 10508065
    Abstract: Methods of preparing oligomers of an olefin are provided. The methods can include providing an alkylaluminum compound and irradiating the alkylaluminum compound with microwave radiation to provide an irradiated alkylaluminum compound. The methods can further include mixing the irradiated alkylaluminum compound with a chromium compound, a pyrrole compound, and a zinc compound to provide a catalyst composition. The methods can further include contacting an olefin with the composition to form oligomers of the olefin. The olefin can include ethylene, and the oligomers of the olefin can include 1-hexene.

  • Publication number: 20190144357
    Abstract: The present invention relates to a method of preparing ?-olefins by oligomerization of C2-C4 olefins. The method is carried out by oligomerization of C2-C4 olefins in the presence of a catalyst system comprising a transition metal source, an activator, which is an alkylaluminoxane, and a compound of formula (I), Ar1Ar2P—N(R)—PAr3Ar4 [formula I], wherein Ar1-4 are the same or different and are selected from substituted or unsubstituted C6-C10 aryl, R is selected from linear or branched C1-C4 alkyl, substituted or unsubstituted C6-C10 aryl, and substituted or unsubstituted C3-C10 cycloalkyl, wherein the oligomerization is carried out in a solvent, which is a bicyclic compound or a mixture of bicyclic compounds, preferably decalin. The claimed method provides a significant increase in the activity of the catalyst during the oligomerization process and, as a consequence, a reduction in the catalyst unit consumption, as well a reduction in the formation of polymer by-product.

  • Patent number: 9586874
    Abstract: The invention relates to the production of olefin oligomers by a method of oligomerization of olefins, and, in particular, to a method of isolating olefin oligomerization products and decomposing the oligomerization catalyst residues. The method of isolating products of an oligomerization reaction of olefins including a terminal double bond, in which the reaction is carried out by the action of a catalyst having chromium compounds, a nitrogen-containing ligand and organoaluminum compounds, includes a step of isolating independent olefin products and a step of treating catalyst residues. Further, the method includes the following sequential steps: a) isolating at least one liquid product of the oligomerization reaction of olefins from an output stream of an oligomerization reactor; b) treating a residue with an aqueous solution of an acid; and c) separating an organic layer and an aqueous layer.

  • Patent number: 8921251
    Abstract: The invention relates to the field of producing polymers and copolymers of olefin oligomers produced by a trimerization reaction of olefin monomers. There is disclosed a process which comprises producing olefin oligomers with the aid of a trimerization catalyst system prepared using UHF irradiation for activating individual components of the trimerization catalyst system. The use of the trimerization catalyst system thus improved and having increased activity provides for increased effectiveness in the production of olefin oligomers from ethylene or other olefin monomers, inter alia, at a low pressure of ethylene. The olefin oligomers thus produced are then polymerized or copolymerized using processes known in the art. The technical effect consists in increasing the effectiveness of the production of olefin oligomers which are then used in a polymerization or copolymerization reaction.
