Hydrodesulfurization of hydrocarbon oils using novel ' phosphorus treated carbon ' supported metal sulfide catalysts

摘要

The present invention relates to a novel " phosphorus treated carbon " support which consists primarily of phosphorus which binds primarily to the carbon surface as a polyphosphate species characterized by peaks between-5 and-30 ppm in the solid state magic angle spin 31p nuclear magnetic resonance spectrum Maintaining a sulfided metal catalyst layer comprising at least one Group 8 metal, at least one metal selected from tungsten and molybdenum; Which comprises bringing a hydrocarbon feed charged in the presence of hydrogen into contact with the catalyst under hydrotreating conditions to effect simultaneous hydrogenation dearomatic reaction, hydrodesulfurization reaction and hydrodenitrogenation reaction, containing an undesirable aromatic component, sulfur and nitrogen compound Hydrodesulfurization and hydrodenitrogenation of packed hydrocarbon oils which are produced by the process of the present invention.
