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 comprising: forming a first reaction mixture having a pH from about 1 to about 6, the first reaction mixture 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, at least a silicon component, at least an aluminum component, and at least a magnesium component; adding a basic alkali component to form a second reaction mixture having a pH between 7 to 12; reacting the second reaction mixture for a time sufficient forming a precipitate or cogel; performing a solid-liquid separation to collect the unsupported catalyst precursor; and drying the unsupported catalyst precursor at a temperature of less than 200° C. forming the catalyst precursor having the 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.
