The invention relates to a method for the elimination of sulfur compounds from the diesel fraction, which is characterized in that an oxidizing reaction of said sulfur compounds is carried out by using at least one organic-inorganic composite as catalyst, said composite comprising Si, Ti and silicon bonded to carbon, and organic and inorganic hydroperoxides as oxidizing agents. According to the inventive method, said organic-inorganic composite can be obtained by a method that comprises a silylation step during synthesis or by a method comprising a post-synthesis silylation step.
La présente invention concerne un procédé destiné à l'élimination de composés soufrés contenus dans une fraction diesel. Ce procédé consiste à réaliser une réaction d'oxydation desdits composés soufrés à l'aide d'au moins un composite organique/inorganique utilisé comme catalyseur, renfermant au moins du Si, du Ti et un mélange de silicium et de carbone, et à utiliser des hydroperoxydes organiques et inorganiques comme agents oxydants. Selon le procédé de la présente invention, le composite organique/inorganique peut être obtenu à l'aide d'un procédé comprenant une étape de silylation lors de la synthèse ou bien à l'aide d'un procédé comprenant une étape de silylation post-synthétique.
