Реферат: This invention concerns a method of olefin metathesis comprising the exposure of said olefins to a catalyst previously activated by heating to a temperature of between 100 and 1000°C in a non-reducing gas atmosphere, said catalyst comprising at least one inorganic material comprising at least two spherical elementary particles, each of said spherical elementary particles comprising oxidised metal particles at most 300 nm in size and containing at least one metal chosen from tungsten, molybdenum, rhenium, cobalt, tin, ruthenium, iron and titanium either taken alone or in a mixture, said oxidised metal particles being present in a mesostructured matrix on the basis of the oxide of at least one element Y chosen from silicon, aluminium, titanium, tungsten, zirconium, gallium, germanium, tin, antimony, lead, vanadium, iron, manganese, hafnium, niobium, tantalum, yttrium, cerium, gadolinium, europium and neodymium and the mixture of at least two of these elements, said mesostructured matrix having a pore size of between 1.5 and 50 nm and having amorphous walls of a thickness of between 1 and 30 nm and said spherical elementary particles having a maximum diameter of 200 μητι.
