Abstract
An improved hydroprocessing catalyst having improved morphology/dispersion characteristics is provided. The hydroprocessing catalyst has the formula (Mt)a(Lu)b(Sv)d(Cw)e(Hx)f(Oy)g(Nz)h, wherein M is at least one group VIB metal; L is optional and if present, L is at least one Group VIII non-noble 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; 0=<b 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). The catalyst is prepared by a process in which at least a sulfur additive is added to the sulfidation process in forming the catalyst precursor.
