Howell, J A

A hydrotreating process is described comprising the steps of: (1) contacting (a) a substantially liquid hydrocarbon-containing feed stream, which also contains at least about 3 ppmw nickel, at least about 5 ppmw vanadium and at lest about 0.5 weight-% Ramsbottom carbon residue, simultaneously with (b) a free hydrogen containing gas and (c) a fixed bed containing a solid, substantially unpromoted inorganic refractory material selected from the group consisting of alumina, silica, magnesia, metal silicates, metal aluminates, aluminosilicates, aluminum phosphate and mixtures thereof, under such contacting conditions as to produce an intermediate liquid product stream having a lower content of nickel and vanadium than the hydrocarbon-containing feed stream; and (2) heating at least a portion of the intermediate liquid product stream in the presence of a free hydrogen containing gas under hydrovisbreaking conditions as to obtain a liquid product containing less Ramsbottom carbon residue and less hydrocarbon material boiling in excess of about 1000/sup 0/F at 1 atm than the intermediate liquid product stream obtained in step (1).
