ABSTRACT:
A process for the production of C.sub.8 alkene isomers by the oligomerization of light olefins to heavier olefins is improved by the addition of heavy paraffins to the oligomerization zone. The recycle of the heavy paraffins improves the selectivity of the oligomerization for C.sub.8 olefin isomers that have a high octane number when saturated and reduces catalyst fouling. The saturated octane number of the resulting C.sub.8 isomers is particularly improved when the oligomerization zone is operated at reduced temperature conditions.
