ABSTRACT:
In a process for the concomitant hydrogenation of aromatics and sulfur-bearing hydrocarbons in an aromatics- and sulfur-bearing, diesel boiling-range hydrocarbon feedstock, the feedstock is contacted at a temperature between about 600.degree. F. and about 750.degree. F. and a pressure between about 600 psi and about 2500 psi in the presence of added hydrogen with a first catalyst bed containing a hydrotreating catalyst containing nickel, tungsten and optionally phosphorous supported on an alumina support, and, after contact with the first catalyst bed, the hydrogen and feedstock without modification, is passed from the first catalyst bed to a second catalyst bed where it is contacted at a temperature between about 600.degree. F. and about 750.degree. F. and a pressure between about 600 psi and about 2500 psi with a hydrotreating catalyst containing cobalt and/or nickel, molybdenum and optionally phosphorous supported on an alumina support.
