Abstract
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 .sup.31 p 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.
