Abstract

A hydroprocessing bulk catalyst is provided. A process to prepare hydroprocessing bulk catalysts is also 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; promoter 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, L, 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 has an X-ray powder diffraction pattern with at least one broad diffraction peak at any of Bragg angles: 8 to 18°, 32 to 40°, and 55 to 65° (from 0 to 70° 2-θ scale). In one embodiment, the catalyst is prepared by sulfiding at least one Group VIB metal compound and optionally at least one group VIII metal compound with a sulfiding agent forming a catalyst precursor; and mixing the catalyst precursor with a hydrocarbon compound to form the hydroprocessing catalyst composition.
