Abstract:
1. A process for preparing a catalyst composition comprising: i) providing a catalyst precursor comprising at least two metal precursors of different “d” block element metals in a solvent carrier, wherein the at least two metal precursors of different “d” block element metals are selected from the group consisting of iron(III) nitrate, zinc nitrate, ferric sulfide, ferrouos sulfide, iron sulfide, zinc sulfide, ferric sulfate, ferric nitrate, ferric phosphate, nickel sulfate, nickel nitrate, nickel phosphate, nickel acetate, and mixtures thereof; ii) combining the catalyst precursor with a sulfiding agent and a hydrocarbon feedstock, forming at least a sulfided catalyst having a 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 selected from the group consisting of titanium, chromium, manganese, iron, cobalt, nickel, copper and zinc; L is at least a “d” block element metal different from the “d” block element metal M; 0<=i<=1; 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), 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.
