A method for processing an oligomerization product stream includes discharging the oligomerization product stream from an oligomerization reactor through a product outlet line, and heating the oligomerization product stream, heating a wall of the product outlet line, or both. The oligomerization product stream includes solvent, linear alpha olefins, a polymer byproduct, or a combination of at least one of the foregoing. The heating is to a temperature that is greater than the melting temperature of the polymer byproduct present in the oligomerization product stream.

Method for processing an oligomerization product stream

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 (R) (R)N&#x2014;P(R)&#x2014;N(R)&#x2014;P(R)&#x2014;N(R)(R), wherein R, R, R, R, R, Rand Rare each independently hydrogen, halogen, amino, trimethylsilyl or C-Chydrocarbyl, preferably straight-chain or branched C-Calkyl, phenyl, C-Caryl or C-Calkyl-substituted phenyl.

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.
