Abstract: A feed mixture comprising at least one C3 olefin and/or at least one C4 olefin may be contacted with a zeolite catalyst under oligomerization reaction conditions to form a product mixture comprising a plurality of olefin oligomers. The zeolite catalyst, optionally with one or more further modifications, may be selected for operability at high WHSV values that may produce at least C12 olefins in the product mixture having an average branching index of about 2.2 or less, such as about 1.3 to about 2.0. Under suitable conditions, C10-C13 olefins may comprise at least about 25% of the product mixture, based on total olefin oligomers. Percentage conversion of the at least one C3 olefin and/or at least one C4 olefin may impact the average branching index of C12 olefin oligomers and selectivity for C10-C13 olefin oligomers. An amount of C4 olefin in the feed mixture may produce a targeted selectivity for C12 olefins.

Abstract: A process for olefin oligomerization can include: contacting a feedstock comprising at least one C3 to C20 olefin/paraffin under oligomerization conditions in the presence of a Si/Al ZSM-23 catalyst having no amine treatment and a Si/Al2 molar ratio of 20 to 60 and/or a Si/Al/Ti ZSM-23 catalyst having no amine treatment, a Si/Al2 molar ratio of 20 to 60, and a Ti/Al molar ratio of 0.1 to 3; and recovering an oligomeric product comprising dimers having a branching index of less than 2.1, trimers having a branching index of less than 2.1, and tetramers having a branching index of less than 2.1.

Abstract: A process for olefin oligomerization can include contacting a feedstock comprising Cn and C2n olefins/paraffins under oligomerization conditions in the presence of an oligomerization catalyst, wherein n is 2 to 15; and recovering an oligomeric product comprising C3n oligomers having a branching index of less than 2.1. Optionally, the feedstock can further comprise C3n olefins/paraffins.
