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) microcrystallites of metal sulfide of a me
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) microcrystallites 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 process for preparing a catalyst comprising a mixture of (i) an amorphous sulfide of trivalent chromium, (ii) micorcrystallites of a metal sulifide of a metal selected from the group consisting of Mo, W, and mixtures thereof, and (iii) a sulfide of at least one promoter metal selected from the gro
A process for preparing a catalyst comprising a mixture of (i) an amorphous sulfide of trivalent chromium, (ii) micorcrystallites of a metal sulifide of a metal selected from the group consisting of Mo, W, and mixtures thereof, and (iii) a sulfide of at least one promoter metal selected from the group consisting of Ni, Co, Mn, Zn, Cu, mixtures thereof and mixtures thereof with Fe, said process comprising heating a precursor at a temperature of at least aobut 200°C., in the presence of sulfur and under oxygen free connditions for a time sufficient to form said catalyst, wherein said precursor comprises a mixture of (i) a hydrated oxide of trivalent chromium and (ii) a thiometallate salt of the general formula (ML)(MoyW1-yS4) wherein M is one or more of the divalent promoter metals selected from the group consisting of Ni, Co, Mn, Zn, Cu, mixtures thereof and mixtures thereof with Fe, wherein Y is any value ranging from 0 to 1, L is one or more neutral, nitrogen-containing ligands, at least one of which is a chelating polydentate ligand.
