ABSTRACT:
The object of the present invention is a process for the elimination of sulphur compounds from the gasoline fraction, characterized in that it comprises carrying out an oxidation reaction of said sulphur compounds using at least one organic-inorganic composite as a catalyst which comprises at least:Si,Ti andsilicon linked to carbon and using organic or inorganic hydro-peroxides as oxidating agents.According to the process for the present invention, said organic or inorganic composite is obtained by means of a process that comprises a sililation stage during synthesis or by means of a process that comprises a post-synthesis sililation stage.
