Abstract

Provided is an improved process for olefin oligomerization allowing one to realize superior selectivity. The process comprises contacting a hydrocarbon feed comprised of straight and branched chain olefins under oligomerization conditions with a catalyst comprising delaminated SSZ-70. The delaminated SSZ-70 offers a zeolite layer with a single unit cell of thickness in one dimension, allowing for elimination of mass transfer in comparison with regular SSZ-70. The result is superior selectivity.
