Moorehead, E L; Shen, S Y

A process is described for producing a premium lubricating base oil from a full-range shale oil or fraction thereof, which process comprises: (1) hydrotreating a nitrogen-containing or sulfur-containing full-range shale oil or fraction thereof containing components boiling above 650/sup 0/F, in the presence of hydrogen and a hydrotreating catalyst under conditions of elevated temperature and pressure which reduce the nitrogen content or sulfur content thereof; (2) hydrodewaxing the resultant hydrotreated shale oil product in the presence of hydrogen and a hydrodewaxing catalyst containing a crystalline molecular sieve under conditions of elevated temperature and pressure which reduce the pour point thereof; and (3) hydrogenating the resultant hydrodewaxed shale oil product in the presence of hydrogen and a hydrogenating catalyst consisting essentially of one or more hydrogenation components on an amorphous support under conditions of elevated temperature and pressure producing at least one lubricating base oil fraction having a pour point no greater than + 10/sup 0/F and a viscosity index of at least 95. The lubricating base oil fraction is boiling above 650/sup 0/F.
