Abstract

A hydroprocessing catalyst 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 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; 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 at least one diffraction peak is greater than 2 degrees wide at ½ height.
