摘要： A process for producing alpha-olefins comprising contacting an ethylene feed with an oligomerization catalyst system, the catalyst system comprising a metal-ligand complex and a co-catalyst, in an oligomerization reaction zone under oligomerization reaction conditions, the reaction conditions comprising a first reaction temperature of at least 70 °C, to produce a product stream comprising alpha-olefins and higher molecular weight oligomers and optionally polyethylene wherein after a first time period, the presence of higher molecular weight oligomers and optionally polyethylene reduces the flow rate through the reaction zone, fouls the reactor surface and/or reduces heat transfer and after that first time period, increasing the temperature of the reaction zone to a second reaction temperature that is at least 5 °C greater than the first reaction temperature for a second time period.

摘要： Metallocene complexes represented by structure (I) are useful for alpha olefin oligomerization in the presence of an activator to generate polyalphaolefins having a high percentage of vinylidene termination and relatively low Mn values. M is a group 4 transition metal. A is a bridging group having one bridging atom extending between a first indenyl ring and a second indenyl ring. Each X is independently an anionic ligand, or two Xs are joined and bound to M to form a metallocycle ring, or two Xs are joined to form a chelating ligand, a diene ligand, or an alkylidene ligand. R1, R1', R3, R3', R4, R4', R7 and R7' are hydrogen. R5, R5', R6, and R6' are independently a C1-C10, optionally substituted, hydrocarbyl group, or R5 and R6 and/or R5' and R6' are bonded together to form an optionally substituted hydrocarbyl ring structure.

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.
