Patent ID: 7288182

Claim:
A process for hydroprocessing a petroleum feedstock, which feedstock contains both nitrogen and sulfur, which process comprises contacting a feedstock with a bulk multimetallic catalyst comprised of at least one Group VIII non-noble metal and at least one Group VIB metals and wherein the ratio of Group VIB metal to Group VIII non-noble metal is from about 10:1 to about 1:10, provided that the bulk multimetallic catalyst is represented by the formula: (X) b (Mo) c (W) d O z wherein X is a Group VIII non-noble metal, the molar ratio of b:(c+d) is 0.5/1 to 3/1, and z=[2b+6(c+d)]/2, which process is performed at temperatures from about 260° C. to about 427° C. (500° F. to about 800° F.), pressures from about 791 to about 6996 kPa (100 to about 1000 psig), gas rates from about 89 to about 1780 m 3 /m 3 (500 to about 10,000 standard cubic feet per barrel), and feed rates from about 0.1 to about 100 liquid hourly space velocity.
