摘要： Selective hydrodesulfurization of cracked naphtha, with minimum attendant hydrogenation of olefins, is effected over a novel catalyst composition comprising a sulfided, "manganese oxide octahedral molecular sieve" supported catalyst bearing (i) at least one non-noble Group VIII metal, (ii) at least one Group VI-B metal, optionally (iii) at least one metal of Group I-A, II-A, III-B, or the lanthanide series of rare earths, and optionally (iv) at least one metal of Group I-B. The catalyst of the present invention is highly selective in minimizing the olefin saturation and the resulting octane loss in the cracked naphtha hydrodesulfurization process.

摘要： A process for treating a hydrocarbon oil feed to reduce total acid number (TAN) and increase API gravity employs a catalyst which includes one or more metals of non-noble Group VIII of the periodic table (e.g., iron, cobalt and nickel), and at least one metal selected from Group VIB (e.g., chromium, tungsten and molybdenum) on a 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. The process includes blending the catalyst with the hydrocarbon oil feed to form a slurry which is then treated with hydrogen at moderate temperature and pressure in, for example, a tubular reactor. Deposit formation is minimized or avoided.
