Abstract
A process for upgrading a hydrocarbon feedstock by hydroprocessing using multi-metallic catalysts is disclosed. In one aspect, the invention relates to hydroprocessing of a hydrocarbon feedstock using a catalyst derived from a catalyst precursor of the formula Av[(MP)(OH)x(L)ny]z(MVIBO4), wherein A comprises an alkali metal cation, an ammonium, an organic ammonium or a phosphonium cation, MP is selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof, L is an organic, oxygen-containing ligand, MVIB is at least one of Group VIB metals, and the atomic ratio of MVIII:MVIB is between 100:1 and 1:100.
