摘要:
The invention relates to a method for the hydrodesulphurisation of at least one diesel fraction, using a catalyst comprising, in the oxide form thereof, at least one metal selected from the group VIB metals and/or at least one metal from the group VIII metals of the periodic table, present in the form of at least one polyoxometalate having formula (HhXxMmOy)q-, wherein: X is an element selected from among phosphorus (P), silicon (Si), boron (B), nickel (Ni) and cobalt (Co), said element being taken alone; M is one or more elements selected from among 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 and 18; y is an integer between 17 and 72; and q is an integer between 1 and 20, said polyoxometalates being present inside a mesostructured silica oxide matrix having a pore size between 1.5 and 50 nm and amorphous walls with a thickness of between 1 and 30 nm. The catalyst is sulphurised prior to use in said method.
摘要:
A process for the hydrocracking a hydrocarbon-containing feedstock in which at least 50% by weight of the compounds have an initial boiling point above 340° C. and a final boiling point below 540° C., using a catalyst having, in its oxide form, at least one metal selected from the metals of groups VIB, VIII and VB, said metals being present in the form of at least one polyoxometallate of formula (HhXxMmOy)q-, said polyoxometallates being present within a mesostructured matrix based on oxide of at least one element Y, said matrix having a pore size between 1.5 and 50 nm and having amorphous walls of thickness between 1 and 30 nm, said catalyst being sulphurized before used in said process.
