A process for simultaneous hydrodearomatization, hydrodesulfurization and hydrodenitrogenation of a charge hydrocarbon oil containing undesired aromatic components, sulfur and nitrogen compounds, which comprises: maintaining a bed of a sulfided metal catalyst comprising one or more metals of non-noble Group VIII, at least one metal selected from tungsten and molybdenum on a novel “phosphorus treated carbon”support, the “phosphorus treated carbon”support being comprised of phosphorus bound to the carbon surface predominantly as polyphosphate species characterized by peaks between -5 and -30 ppm in the solid-state magic angle spinning 31p nuclear magnetic resonance spectrum; passing a charge hydrocarbon feed in the presence of hydrogen into contact with said catalyst at hydrotreating conditions, thereby effecting hydrodearomatization, and simultaneously effecting hydrodesulfurization and hydrodenitrogenation.

A hydroprocessing catalyst composition useful for hydrodesulfurization, hydrodenitrogenation, hydrodearomatization, hydrodeoxygenation, hydrogenation, hydrocracking, hydrofining, hydrodemetallization, and any reaction the purpose of which is to improve the hydrogen to carbon ratio, API gravity, or color of hydrocarbon oils, comprising 0.1 to 15% by weight of one or more metals of non-noble Group VIII selected from iron, cobalt and nickel, and at least one metal selected from 1 to 50% by weight tungsten and 1 to 20% by weight molybdenum or chromium based on the final catalyst weight, on a “phosphorus treated carbon”support, the “phosphorus treated carbon”support being characterized by (1) having been prepared by heat treating mixtures of activated carbon and phosphorus compounds at temperatures greater than 450°C., (2) the phosphorus existing in the “phosphorus treated carbon”being bound to the carbon surface predominantly as polyphosphate species characterized by peaks between -5 and -30 ppm in the solid-state magic angle spinning 31p nuclear magnetic resonance spectrum, and (3) having a B.E.T. surface area of between 100 m2/g and 2000 m2/g, a total pore volume for nitrogen of at least 0.3 ml/g, and an average pore diameter of between 12 Angstroms and 100 Angstroms.
