In a process for the concomitant hydrogenation of aromatics and sulphur-bearing hydrocarbons in an aromatics- and sulphur-bearing, diesel boiling-range hydrocarbon feedstock, the feedstock is contacted at a temperature between 315 and 399 °C and a pressure between 40 and 168 bar 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 315 and 399 °C and a pressure between 40 and 168 bar with a hydrotreating catalyst containing cobalt and/or nickel, molybdenum and optionally phosphorous supported on an alumina support.
