This patent describes a process for the concomitant hydrogenation of aromatics and sulfur-bearing hydrocarbons in an aromatics- and sulfur-bearing hydrocarbon feedstock having substantially all of this components boiling in the range of abut 200{degrees}F to about 900{degrees}F. It comprises: contacting at a temperature between about 600{degrees}F. and abut 750{degrees}F and a pressure between about 650 psi and about 2500 psi in the presence of added hydrogen the feedstock with a first catalyst bed containing a hydrotreating catalyst comparing nickel, tungsten and phosphorous on an alumina support, in which the nickel content ranges from 1 to 5 percent by weight of the total catalyst, measured as the metal, the tungsten content ranges from 10 to 35 percent by weight of the total catalyst measured as the metal and the phosphorus content ranges from 1 to 5 percent by weight of the total catalyst; passing the hydrogen and feedstock without modification, from the first catalyst bed to a second catalyst bed where it is contacted at a temperature between about 600{degrees} F. and abut 750{degrees} F. and a pressure between about 600 psi and about 2500 psi with a hydrotreating catalyst comprising a hydrogenating metal component selected from cobalt, nickel and mixtures thereof, molybdenum and phosphorus on an alumina support, in which the hydrogenating metal component content ranges from 1 to 5 percent by weight of the total catalyst, measured as the metal, the molybdenum content ranges from 8 to 20 percent by weight of the total catalyst, measured as the metal and the phosphorus content ranges from 1 to 5 percent by weight of the total catalyst.
