Abstract: A method for purifying 1-hexene is disclosed. The method can include contacting a first stream containing 1-hexene and 2-ethyl-1-butene with an isomerization catalyst containing an comprising an alumina, silica-alumina, a zeolite, or an ion exchange resin, or any combinations thereof, under conditions sufficient to selectively isomerize at least a portion of 2-ethyl-1-butene into 3-methyl-2-pentene and form a second stream containing 1-hexene and 3-methyl-2-pentene, and separating the second stream into a third stream containing 1-hexene and a fourth stream containing 3-methyl-2-pentene.

Abstract: The disclosure provides a method of purifying a linear alpha olefin product, the method including feeding a linear alpha olefin feed stream comprising the linear alpha olefin product and at least one impurity into a distillation column, the distillation column having a plurality of stacked stages; withdrawing a side stream from at least one of said plurality of stacked stages; feeding the side stream into a reactor containing an isomerization catalyst to convert at least a portion of the at least one impurity from a first isomer to a second isomer, producing a reactor product stream having a reduced content of the first isomer; returning the reactor product stream to a stage of the distillation column; and withdrawing an overhead stream from the distillation column comprising the linear alpha olefin product and having a reduced content of the at least one impurity.

Abstract: The present disclosure relates to a catalyst composition for the oligomerization of ethylene comprising a zirconium-containing catalyst and an organoaluminum-containing co-catalyst. The disclosure also relates to a process for oligomerization of ethylene in the presence of the catalyst composition according to the disclosure. The disclosed process results in C4-C20 linear alpha olefins having improved linearity.

Abstract: A method for removal of an organic amine from a hydrocarbon stream includes mixing the hydrocarbon stream including the amine with an aqueous inorganic acid in a volumetric ratio of hydrocarbon stream: aqueous inorganic acid of greater than 1.5:1 to 5:1, phase separating a hydrocarbon phase and an aqueous phase, removing the hydrocarbon phase, mixing the aqueous phase with an aqueous alkaline solution, phase separating the aqueous phase and an organic phase, and removing the organic phase. The aqueous inorganic acid has a concentration of greater than or equal to 30 weight percent. The disclosed method results in improved phase separation time during an amine removal process.
