Abstract: The disclosure provides a catalytic process for selective isomerization of 2-ethyl-1-butene in a linear alpha olefin stream that includes feeding a linear alpha olefin stream comprising a linear alpha olefin and 2-ethyl-1-butene to a reactor housing a modified alumina catalyst to isomerize at least a portion of the 2-ethyl-1-butene to cis- or trans-3-methyl-2-pentene, the period during which said feeding occurs being time on stream; withdrawing an effluent from the reactor containing less 2-ethyl-1-butene than the linear alpha olefin stream; and periodically regenerating the modified alumina catalyst by introducing a non-oxidizing environment to the reactor at time on stream intervals of no more than about 200 hours, wherein the reactor is subjected to the non-oxidizing environment for a time period of about 15 hours or greater and wherein the non-oxidizing environment has a temperature of about 250° C. or greater for at least a portion of the time period.

Abstract: The present disclosure provides for processes and catalysts for enhancing a linear alpha-olefin product stream from an oligomerization reaction. A catalyst composition including a first zeolite and a second zeolite is provided, the first and second zeolites each having an average pore size of greater than about 6 ?, wherein the catalyst composition has a Brönsted Acid Site (BAS) equivalent of about 1.0 mmol/g catalyst or less, and wherein the first zeolite is at least partially metal ion-exchanged and the second zeolite is at least partially in H+ form. A process for producing a purified linear-alpha olefin (LAO) is also provided, which includes introducing a LAO product stream comprising an alkyl-butene fraction into a catalyst bed comprising a zeolite catalyst and in fluid connection with the LAO product stream to catalytically isomerize the alkyl-butene fraction into an alkyl-pentene fraction.

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: A method for purifying 1-hexene is disclosed.
