The present invention is a process for hydrocracking at least one hydrocarbon feedstock wherein at least 50% by weight of the compound has an initial boiling point above 340 ° C. and an end point below 540 ° C. In a form, a catalyst comprising at least one metal selected from Group VIB metal, Group VIII metal and Group VB metal of the periodic table, alone or in a mixture, is used, said metal having the formula (H h X x M m O y ) q- exists in the form of at least one polyoxometalate, where X is phosphorus (P), silicon (Si), boron (B), nickel (Ni) and An element selected from cobalt (Co), which is used alone; M is vanadium (V), niobium (Nb), tantalum (Ta), molybdenum (Mo), tungsten (W), nickel Ni) and one or more elements selected from cobalt (Co); O is oxygen; H is hydrogen; h is an integer from 0 to 12; x is from 0 to 4 M is an integer equal to 5, 6, 7, 8, 9, 10, 12 and 18; y is an integer from 17 to 22; q is an integer from 1 to 20; The polyoxometalate is an oxide-based mesostructured matrix of at least one element Y selected from the group comprising silicon, aluminum, titanium, zirconium, gallium and cerium and a mixture of at least one of the elements It relates to a method that exists within. The matrix has an amorphous wall with a pore size of 1.5-50 nm and a thickness of 1-30 nm, and the catalyst is sulfided prior to use in the process. |
