초록▼
A catalyst composition comprising an amorphous sulfide 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 is prepared by heating one or more precursors
A catalyst composition comprising an amorphous sulfide 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 is prepared by heating one or more precursors at a temperature of at least about 200°C. under oxygen-free conditions in the presence of a sulfur, wherein said precursor is selected from the group consisting of [Cr1-zMzLXy](MoS4)n, [Cr1-zMzLXy](WS4)n and mixtures thereof, wherein M is one or more divalent promoter metals selected from the group consisting of Mn, Fe, Co, Ni, Cu, Zn and mixtures thereof, wherein L is one or more neutral nitrogen-containing ligands, wherein ligand X is a singly-charged anionic species and wherein 1>z≥0, 1-z≥y≥0, and wherein n equals (3-z-y)/2. These compositions have been found to be good hydroprocessing catalysts, particularly hydrotreating catalysts exhibiting a very high hydrodenitrogenation activity and/or selectivity in nitrogen and sulfur-containing hydrocarbon feeds.
