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)nyz(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 met...
1. A process for hydroprocessing a hydrocarbon feedstock which comprises contacting the feedstock with an unsupported catalyst under hydroprocessing conditions, wherein the catalyst is prepared by drying at a temperature of 200° C. or less, then sulfidizing an unsupported charge-neutral hydroxide catalyst precursor composition of the formula: Av[(MP)(OH)x(L)ny]z(MVIBO4), wherein A is at least one of an alkali metal cation, an ammonium, an organic ammonium and a phosphonium cation,MP is at least one of a Group VIII metal, Group IIB metal, Group IIA metal,...
