In a process for oligomerizing a Cto Cn-olefin feedstock over surface deactivated ZSM-23, the feedstock contains from about 0.1 wt % to about 25 wt % of an iso-olefin and the C+ fraction of the oligomerized olefin product contains less than 0.5 atom % of quaternary carbon atoms.

Olefin oligomerization process

A selectivated molecular sieve, e.g., ZSM-22 or ZSM-23, is used as olefin oligomerization catalyst to provide product, e.g., octenes and dodecenes from butene, having a low degree of branching and hindered double bonds.
