  • Process for oligomer production and saturation
    Patent number: 6080903
    Abstract: A process for the production of C.sub.8 and higher carbon number alkene oligomers 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 extends the catalyst activity and improves the catalyst life. The non-reactive paraffin stream may be recycled through the process with minimal losses and make-up.
