ABSTRACT:
Catalytic dewaxing of a waxy component-containing hydrocarbon feed is accomplished with improved selectivity employing, as catalyst, a zeolite the surface acid catalytic activity of which has been at least partially reduced by chemisorption of a surface-deactivating agent such as a bulky amine thereon. The invention is especially useful for the hydrodewaxing of a waxy lube range product to provide a high viscosity index, low pour point, low cloud point lubricating oil product.
