Patent number: 9376636
Abstract: A process of hydrodesulphuration of at least one gasoline cut implementing a catalyst comprising, 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?, wherein X is an element selected from phosphorus, silicon, boron, nickel and cobalt, M is one or more element(s) selected from molybdenum, tungsten, nickel and cobalt, h is an integer from 0-12, x is an integer from 0-4, m is an integer 5, 6, 7, 8, 9, 10, 11, 12 and/or 18, y is an integer of 17-72 and q is an integer of 1-20, the polyoxometalates being present within a mesostructured silicon oxide matrix having a pore size of 1.5-50 nm and having amorphous walls of thickness 1-30 nm, the catalyst being sulphured before use in the process.

Abstract: An inorganic material is described, constituted by at least two elementary spherical particles, each of said spherical particles comprising metallic nanoparticles having at least one band with a wave number in the range 750 to 1050 cm?1 in Raman spectroscopy and containing one or more metals selected from vanadium, niobium, tantalum, molybdenum and tungsten, said metallic nanoparticles being trapped in a mesostructured matrix based on an oxide of an element Y selected from silicon, aluminium, titanium, tungsten, zirconium, gallium, germanium, tin, antimony, lead, vanadium, iron, manganese, hafnium, niobium, tantalum, yttrium, cerium, gadolinium, europium and neodymium. Said matrix has pores with a diameter in the range 1.5 to 50 nm and amorphous walls with a thickness in the range 1 to 30 nm. Said elementary spherical particles have a maximum diameter of 200 microns and said metallic nanoparticles have a maximum dimension strictly less than 1 nm.
