Abstract

A hydroprocessing bulk catalyst is provided. A process to prepare hydroprocessing bulk catalysts is also provided. The hydroprocessing catalyst has the formula (Rp)i(Mt)a(Lu)b(Sv)d(Cw)e(Hx)f(Oy)g(Nz)h, wherein M is at least at least a “d” block element metal; L is also at least a “d” block element metal, but different from M; 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); R is optional and in one embodiment, R is a lanthanoid element metal; 0<=i<=1; pi+ta+ub+vd+we+xf+yg+zh=0; 0<b; 0<b/a=<5; 0.5(a+b)<=d<=5(a+b); 0<e<=11(a+b); 0<f<=7(a+b); 0<g<=5(a+b); 0<h<=2(a+b). The catalyst has an X-ray powder diffraction pattern with at least three diffractions peak located at 2-θ angles of greater than 25°. In one embodiment, the catalyst is prepared by forming at least a sulfided catalyst precursors from at least two “d” block element metals; and mixing the catalyst precursor with a hydrocarbon compound to form the hydroprocessing catalyst composition. In another embodiment, the catalyst is prepared by the thermal decomposition of an oil dispersible sulfur containing organic metal precursor upon contact with a hydrocarbon oi…
