Claim Text:
1. A process for hydrocracking at least one hydrocarbon-containing feedstock, in which at least 50% by weight of the compounds boil between 340° C. and 540° C., by a catalyst comprising, in its oxide form, at least one metal selected from the group consisting of the metals of group VIB, the metals of group VIII and the metals of group VB of the periodic table, alone or in a mixture, said metals being present in the form of at least one polyoxometallate of formula (H h X x M m O y ) q− in which X is an element selected from the group consisting of phosphorus (P), silicon (Si), boron (B), nickel (Ni) and cobalt (Co), said element being alone, M is one or more element(s) selected from the group consisting of vanadium (V), niobium (Nb), tantalum (Ta), molybdenum (Mo), tungsten (W), nickel (Ni) and cobalt (Co), O is oxygen, H is hydrogen, h is an integer between 0 and 12, x is an integer between 0 and 4, m is an integer equal to 5, 6, 7, 8, 9, 10, 11, 12 or 18, y is an integer between 17 and 72 and q is an integer between 1 and 20, said polyoxometallates being present within a mesostructured matrix based on oxide of at least one element Y selected from the group consisting of silicon, aluminium, titanium, zirconium, gallium, and cerium and a mixture of at least one of these elements, said matrix having a pore size between 1.5 and 50 nm and having amorphous walls of thickness between 1 and 30 nm, said polyoxometallates present within said matrix are trapped in the walls of said matrix, said catalyst having been sulphurized.
