A catalyst precursor composition and methods for making such catalyst precursor are disclosed. The catalyst precursor comprises at least a metal compound selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof, at least one Group VIB metal, at least one organic, oxygen-containing ligand, and a cellulose-containing material. Catalysts prepared from the sulfidation of such catalyst precursors are used in the hydroprocessing of hydrocarbon feeds. In one embodiment, the sulfidation is carried out by contacting the catalyst precurso...
What is claimed is: 1. A process for forming catalyst composition prepared from an unsupported catalyst precursor composition having a formula Av[(MP)(OH)x(L)ny]z(MVIBO4), the process comprises: co-precipitating at reaction conditions to form a precipitate or cogel-precursor: at least one of a Group VIB metal compound MVIB, at least a metal compound MP selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof, and at least one of an organic oxygen-containing ligand; wherein the precursor has the formula Av[(MP)(OH)x(L)ny]z(MVIBO...
