Abstract:
1. A process for hydroprocessing a hydrocarbon feedstock which comprises contacting the hydrocarbon feedstock with a catalyst under hydroprocessing conditions, wherein the catalyst is formed by sulfiding an unsupported catalyst precursor composition having a formula A wherein A is at least one of an alkali metal cation, an ammonium, an organic ammonium and a phosphonium cation, M L is at least one organic oxygen-containing ligand, M M v−2+P*z−x*z+n*y*z=0; and 0<y≦−P/n; 0<x≦P; 0<v≦2; 0<z; and wherein the unsupported catalyst precursor has an X-ray diffraction pattern that is amorphous with broad peaks or an X-ray diffraction pattern with at least a crystalline peak at Bragg angle between 52.7° to 53.2° theta.
