Abstract:
1. A process for forming an unsupported catalyst precursor composition having a formula A v [(M P ) (OH) x (L) n y ] z (M VIB O 4 ), the process comprises the steps of: co-precipitating at reaction conditions forming a precipitate or cogel comprising: at least a metal compound selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof, at least a Group VIB metal compound, at least one organic oxygen-containing ligand, 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 performing a solid-liquid separation to collect the unsupported catalyst precursor.
