    • 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.degree. C. under oxygen-free conditions in the presence of a sulfur, wherein said precursor is selected from the group consisting of [Cr.sub.1-z M.sub.z LX.sub.y ](MoS.sub.4).sub.n, [Cr.sub.1-z M.sub.z LX.sub.y ](WS.sub.4).sub.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.gtoreq.0, 1-z.gtoreq.y.gtoreq.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.
    • 一种催化剂组合物,其包含三价铬的无定形硫化物和选自(a)钼,钨及其混合物的至少一种金属和(b)(a)与Fe,Ni,Co,Mn,Cu, Zn及其混合物通过在无硫条件下在硫存在下在至少约200℃的温度下加热一种或多种前体而制备,其中所述前体选自[Cr1-zMzLXy] (MoS4)n,[Cr1-zMzLXy](WS4)n及其混合物,其中M是一种或多种选自Mn,Fe,Co,Ni,Cu,Zn的二价助催化剂金属及其混合物,其中L 是一种或多种中性含氮配体,其中配体X是单电荷阴离子物质,并且其中n等于(3-zy) )/ 2。 已经发现这些组合物是良好的加氢处理催化剂,特别是在含氮和含硫烃进料中表现出非常高的加氢脱氮活性和/或选择性的加氢处理催化剂。
