Abstract

Hydrocarbon streams containing primarily olefins such as ethylene up to and inclusive of C.sub.16 olefins are converted at elevated pressures to high viscosity index lube oil base stock by contacting them with a ZSM-5 type zeolite catalyst which has been conditioned by previous contact with a light olefin preferably of 3-6 carbon atoms per molecule under suitable conditions of temperature and pressure.
