Abstract: The present invention relates to a catalyst composition and a process for the oligomerization of ethylene to produce 1-hexene or 1-octene, wherein the catalyst composition comprises a chromium compound; an NPNPN ligand of the formula (R1) (R2)N—P(R3)—N(R4)—P(R5)—N(R6)(R7), wherein R1, R2, R3, R4, R5, R6 and R7 are each independently hydrogen, halogen, amino, trimethylsilyl or C1-C20 hydrocarbyl, preferably straight-chain or branched C1-C10 alkyl, phenyl, C6-C20 aryl or C6-C20 alkyl-substituted phenyl.

Abstract: A process for flushing an oligomerization reactor is described, including flushing the oligomerization reactor with a flushing medium comprising C6 linear alpha olefins, C8 linear alpha olefins, C10 linear alpha olefins, or a combination including at least one of the foregoing, to provide a purge stream comprising the C6 linear alpha olefins, C8 linear alpha olefins, C10 linear alpha olefins, or a combination including at least one of the foregoing, and a polymer byproduct of an oligomerization reaction. A process for the oligomerization of an olefin is also described, wherein the process includes oligomerizing the olefin in the reactor to form a reaction product stream comprising linear alpha olefins, and subsequently flushing the oligomerization reactor according to the process disclosed herein.

Abstract: A process for deactivation of an olefin oligomerization catalyst is described, including contacting a catalyst composition with a catalyst quenching medium to form a deactivated catalyst composition, and recovering excess catalyst quenching medium. The catalyst quenching medium includes an alcohol having at least 6 carbon atoms, an organic amine, an amino alcohol, or a combination comprising at least one of the foregoing. The catalyst quenching medium is present in a molar ratio of catalyst quenching medium to catalyst of at least 3:1. A process for the oligomerization of an olefin is also described, including feeding the olefin, a solvent, and a catalyst composition into a reactor, oligomerizing the olefin in the reactor to form a reaction product stream including linear alpha olefins, solvent, and the catalyst composition, and contacting the reaction product stream with a catalyst quenching medium.
