Abstract
A method for hydroprocessing a hydrocarbon feedstock is provided. The method comprises contacting the feedstock with a catalyst under hydroprocessing conditions, wherein the catalyst is formed by sulfiding an unsupported catalyst precursor of the general formula Av[(MP) (OH)x (L)ny]z (MVIBO4), wherein MP is selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof; L is one or more oxygen-containing ligands, and L has a neutral or negative charge n<=0, MVIB is at least a Group VIB metal having an oxidation state of +6; MP:MVIB has an atomic ratio between 100:1 and 1:100; v−2+P*z−x*z+n*y*z=0; and 0≦y≦−P/n; 0≦x≦P; 0≦v≦2; 0≦z. In one embodiment, the catalyst precursor further comprises a cellulose-containing material. In another embodiment, the catalyst precursor further comprises at least a diluent (binder). In one embodiment, the diluent is a magnesium aluminosilicate clay.
