Abstract:
1. A process for preparing a hydroprocessing catalyst composition, which process comprising the steps of: i) combining and reacting at least one Group VIB metal compound (“M”) with at least a metal compound (“Promoter Metal” compound X) selected from a non-noble Group VIII metal, a Group VIIIB metal, a Group VIB metal, a Group IVB metal, and a Group IIB metal to obtain an intermediate mixture; ii) sulfiding the intermediate mixture with a sulfiding agent in solution forming a catalyst precursor; and iii) mixing the catalyst precursor with a hydrocarbon compound to form a hydroprocessing catalyst composition having formula (M wherein subscripts a and b each are suitably greater than 0 such that 0≦b/a≦5, 0≦f≦7(a+b),0≦g≦5(a+b),0≦h≦0.5(a+b), the molar ratio of the sulfiding agent to the at least one Group VIB metal compound M and the at least a Promoter Metal compound X is sufficient for subscript d to have a value of: (a+0.5b)≦d≦(5a+2b), t, u, v, w, x, y, z, each representing total charge for each of: M, X, S, C, H, O and N, respectively, ta+ub+vd+we+xf+yg+zh=0; and the catalyst precursor is mixed with a sufficient amount of hydrocarbon for subscript e to have a value of 0≦e≦11(a+b).
