A process for olefin oligomerization can include: contacting a feedstock comprising at least one Cto Colefin/paraffin under oligomerization conditions in the presence of a Si/Al ZSM-23 catalyst having no amine treatment and a Si/Almolar ratio of 20 to 60 and/or a Si/Al/Ti ZSM-23 catalyst having no amine treatment, a Si/Almolar 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.

Oligomerization of olefins

The disclosure relates to olefin oligomerization processes and related zeolites and structure directing agents. The olefin oligomerization processes can exhibit relatively high conversions. The zeolites can exhibit comparatively high stabilities. The zeolites can have relatively high ratios of external surface area to total surface area. An exemplary zeolite is a beta zeolite having a relatively high ratio of external surface area to total surface area. The disclosure also relates to structure directing agents, and methods of using the structure direction agents to prepare the zeolites.
