METHOD OF OXIDISING SULPHUR COMPOUNDS PRESENT IN GASOLINE, KEROSENE AND DIESEL FRACTIONS

摘要

The invention relates to a method of oxidising sulphur compounds present in gasoline, kerosene and diesel fractions. The inventive method comprises an oxidation step in which a reaction mixture is subjected to a reaction involving the oxidation of said sulphur compounds with an oxidation agent, which is selected from the group consisting of peroxides, inorganic peroxides,, organic peroxides and hydroperoxides, in a liquid phase without the use of a solvent and in the presence of at least one micro-, and/or mesoporous solid catalyst which is selected from among microporous molecular sieves, mesoporous molecular sieves and combinations thereof. Moreover, the invention also comprises a separation step wherein products which have not reacted are separated from products which reacted in the reaction step. The channel diameter of the micro- and/or mesoporous catalyst is greater than 0.6 nm and said catalysts contain Ti in the lattice and in non-lattice positions. <IMAGE>
