ABSTRACT:
A waxy component-containing lubricating oil stock derived from the multi-stage catalytic oligomerization of a lower olefin such as propylene is subjected to selective catalytic hydrodewaxing in the presence of certain acidic zeolites, e.g., H-ZSM-23 and H-ZSM-35, preferably associated with a hydrogenation component such as platinum, palladium or zinc, to provide a high viscosity, low pour point lubricating oil product.
