A composition of matter comprising a mixture of (i) a sulfide of at least one promoter metal selected from the group consisting of Ni, Co, Mn, Cu, Zn and mixture thereof and mixtures thereof with Fe, (ii) an amorphous sulfide of trivalent chromium and (iii) microcrystalline of metal sulfide of a met

A composition of matter comprising a mixture of (i) a sulfide of at least one promoter metal selected from the group consisting of Ni, Co, Mn, Cu, Zn and mixture thereof and mixtures thereof with Fe, (ii) an amorphous sulfide of trivalent chromium and (iii) microcrystalline of metal sulfide of a metal selected from the group consisting of molybdenum, tungsten and mixture thereof. These compositions have been found to be useful hydrotreating catalysts having nitrogen removal activity superior to that of commercial catalysts such as cobalt-molybdate on alumina.

A hydrorefining process for reducing the contents of sulfur and nitrogen compounds in a hydrocarbon feed comprising contacting a hydrocarbon feed at elevated temperature of at least about 100°C. and in the presence of hydrogen, with a catalyst consisting essentially of a mixture of (i) an amorphous sulfide of trivalent chromium, (ii) microcrystallites of metal sulfide of a metal selected from the group consisting of Mo, W and mixture thereof and (iii) a sulfide of at least one promoter metal sulfide of a metal selected from the group consisting of Ni, Co, Mn, Zn, Cu and mixture thereof and mixture thereof with Fe, said contacting occurring for a time sufficient to hydrorefine at least a portion of said feed. A process for hydrocracking a hydrocarbon feed which comprises contacting said feed at an elevated temperature of at least about 150°C. and in the presence of hydrogen with a catalyst consisting essentially of a mixture of (i) an amorphous metal sulfide of trivalent chromium, (ii) microcrystallites of metal sulfide of a metal selected from the group consisting of Mo, W and mixture thereof and (iii) a sulfide of at least one promoter metal selected from the group consisting of Ni, Co, Mn, Cu, Zn and mixture thereof, and mixture thereof with Fe, said contacting occurring for a time sufficient to hydrocrack at least a portion of said feed and wherein said catalyst exhibits no crystallinity for the chromium sulfide when measured by X-ray diffraction. A process for improving the oxidation stability of a nitrogen and sulfur containing lube oil feed which comprises contacting said feed at an elevated temperature of at least about 150°C. and in the presence of hydrogen with a catalyst consisting essentially of a mixture of (i) an amorphous sulfide of trivalent chromium, (ii) microcrystallites of metal sulfide of a metal selected from the group consisting of Mo, W and mixture thereof and (iii) a sulfide of at least one promoter metal selected from the group consisting of Ni, Co, Mn, Zn, Cu and mixture thereof and mixture thereof with Fe, said contacting occurring for a time sufficient to improve the oxidation stability of said lube oil.
