A process for treating a charge hydrocarbon oil containing undesired aromatic components, sulfur and nitrogen compounds, which comprises maintaining a bed of a sulfided catalyst comprising 0.1 to 15% by weight of one or more non-noble Group VIII metals; and from 1 to 50% by weight of tungsten and/or from 1 to 20% by weight or molybdenum or chromium, and 0.01 to 10% by weight of zinc, on an activated carbon support, passing a charge hydrocarbon feed in the presence of hydrogen into contact with said catalyst at hydrotreating conditions, thereby effecting hydrogenation, hydrodearomatization, hydrodesulfurization and hydrodenitrogenation of said charge hydrocarbon feed containing undesired aromatic components, sulfur and nitrogen, and forming a product stream of hydrocarbon containing a lesser concentration of undesired aromatic components, sulfur and nitrogen; and recovering said product stream of hydrocarbon containing a lesser concentration of undesired aromatic components, sulfur and nitrogen.
