Abstract:
1. A process for preparing a catalyst composition comprising: i) providing at least two metal precursors of different “d” block element metals; ii) combining the at least two metal precursors with a sulfiding agent, forming at least a sulfided catalyst precursor; and iii) mixing the at least a sulfided catalyst precursor with a hydrocarbon compound to transform the sulfided catalyst precursor into a catalyst composition having formula (R R is optional, R is at least a lanthanoid element metal or an alkaline earth metal; M is at least a “d” block element metal; L is at least a “d” block element metal different from the “d” block element metal M; p, t, u, v, w, x, y, z, each representing total charge for each of: M, L, S, C, H, O and N, respectively, wherein pi+ta+ub+vd+we+xf+yg+zh=0; wherein the “d” block element is selected from the group consisting of iron, zinc, titanium, nickel, copper, cobalt, chromium, and manganese.
