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 Å, 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.
A catalyst composition comprising a mixture of a first zeolite and a second zeolite and an optional metal oxide binder, the first and second zeolites each having an average pore size of greater than about 6 Å, wherein the catalyst composition comprises a Brönsted Acid Site (BAS) equivalent of about 1.0 mmol/g catalyst or less, and wherein the first zeolite is metal ion-exchanged with one or more metals selected from the group consisting of alkali metals, alkaline earth metals, and combinations thereof and the second zeolite is in H+ form, and wherein the first and second zeolite are present in the mixture at a weight ratio of first zeolite to second zeolite in a range of about 5:1 to about 15:1.
