Abstract
The invention relates to a process of hydrodesulphuration of at least one gasoil cut implementing a catalyst containing, in its oxide form, at least one metal from group VIB and/or at least one metal from group VIII of the periodic table, present in the form of at least one polyoxometalate of the formula (HhXxMmOy)q−, said polyoxometalates being present within a mesostructured silicon oxide matrix having a pore size within the range 1.5 to 50 nm and having amorphous walls of thickness within the range 1 to 30 nm, the said catalyst being sulphured before being implemented in the said process.
