ABSTRACT:
A combination process for producing high viscosity index lubes from light olefins is provided wherein light olefins are first passed over a small pore zeolite and the liquid product therefrom is then processed over an intermediate pore zeolite to provide a lubricating oil with a higher viscosity, high Viscosity Index and low pour point in greater yield than obtained with either of the catalysts alone.
