Abstract
A catalyst precursor composition and methods for making such a catalyst precursor are disclosed. The catalyst precursor comprises at least a promoter metal selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof, having an oxidation state of +2 or +4, at least one Group VIB metal, at least one organic, oxygen-containing ligand, and a cellulose-containing material. In one embodiment, the catalyst precursor is of the formula Av[(MP) (OH)x (L)ny]z (MVIBO4), wherein A is one or more monovalent cationic species, MP is selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof, L is one or more oxygen-containing ligands, MVIB is at least a Group VIB metal, MP:MVIB has an atomic ratio between 100:1 and 1:100. In one embodiment, catalysts prepared from the sulfidation of such catalyst precursors are used in the hydroprocessing of hydrocarbon feeds. In a hydroconversion process at a hydrogen partial pressure of ˜450 psig, the catalyst a 700° F.+ conversion rate of at least 50% of the 700° F.+ conversion results gives obtained under comparable conditions and with a hydrogen partial pressure of 600 psig.
