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 nickel; and from 1 to 50% by weight of tungsten and 0.01 to 10% by weight of phosphorus, on an activated carbon support, and passing a charge hydrocarbon feed in the presence of hydrogen into contact with said catalyst at hydrotreating conditions, thereby effecting 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 quantity of undesired aromatic components, sulfur and nitrogen; and recovering said product stream of hydrocarbon containing a lesser quantity of undesired aromatic components, sulfur and nitrogen.
