ABSTRACT OF THE DISCLOSURE A composition comprising an amorphous sul- fide of trivalent chromium and at least one metal selected from the group consisting of (a) molybdenum, tungsten and mixture thereof and (b) mixtures of (a) with Fe, Ni, Co, Mn, Cu, Zn and mixture thereof and a method for preparing such compositions. These com- positions have been found to be good hydroprocessing catalysts, particularly hydrotreating catalysts ex- hibiting a very high hydrodenitrogenation activity and/or selectivity in nitrogen and sulfur-containing hydrocarbon feeds.
