Abstract:
A process for the production of lubricant oil range hydrocarbon having increased viscosity index by oligomerization of lower olefins over medium pore shape selective acid zeolite catalyst. The preferred oligomerization process is conducted using 50 ppm to 5 weight percent of water vapor as cofeed, based on olefin and acid ZSM-5 zeolite.
