A process to prepare hydroprocessing bulk catalysts is provided. The hydroprocessing catalyst has the formula (Mt)a(Xu)b(Sv)d(Cw)e(Hx)f(Oy)g(Nz)h, wherein M is at least one group VIB metal; X is at least at least a metal compound selected from a non-noble Group VIII metal, a Group VIIIB metal, a Gro
A process to prepare hydroprocessing bulk catalysts is provided. The hydroprocessing catalyst has the formula (Mt)a(Xu)b(Sv)d(Cw)e(Hx)f(Oy)g(Nz)h, wherein M is at least one group VIB metal; X is at least at least a metal compound 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 (“Promoter Metal”); t, u, v, w, x, y, z representing the total charge for each of the components (M, X, S, C, H, O and N, respectively); ta+ub+vd+we+xf+yg+zh=0; and 0=<b/a=<5, (a+0.5b)<=d<=(5a+2b), 0<=e<=11(a+b), 0<=f<=7(a+b), 0<=g<=5(a+b), 0<=h<=0.5(a+b). In one embodiment, the process comprises the steps of: combining and reacting at least one Group VIB metal compound with at least one group VIII non-noble metal compound to obtain an intermediate mixture; sulfiding the intermediate mixture with a sulfiding agent forming a catalyst precursor; and mixing the catalyst precursor with a hydrocarbon compound to form the hydroprocessing catalyst composition.
