A catalytic support includes a substantial quantity of at least one SVI group Periodic Table metal oxide in which is incorporated silica. The mass ratio between the quantity of SVI group metal oxide and the quantity of silica it contains ranges between 5 and 70, the SVI group metal oxide is in crystalline form, and the specific surface of the support is greater than or equal to 160 m /g.

Catalytic support with an oxide base from a metal belonging to the SVI group of the periodic table, its preparation and its uses

A method for obtaining oil products such as diesel fuel with improved quality, from a gas oil fraction containing organosulphur compounds such as dibenzenethiophenes and/or their derivatives, with initial and final boiling points generally ranging between about 170 and 480&deg; C. The method includes at least two steps which consist in: (a) liquid-liquid extraction wherein the diesel fuel fraction is contacted with a solvent so as to obtain a gas oil-type raffinate with low content of sulphur and aromatic compounds and an extract rich in solvent and with high content of sulphur and aromatic compounds; (b) oxidation of the extract sulphur compounds so as to obtain, after separation, a heavy gas oil-type hydrocarbon effluent with low sulphur content, and a residue comprising oxidased organosulphur compounds. The invention also concerns oil products obtained by said method which can be used either for the formation of fuel for internal combustion engine with compression ignition (of the diesel type) or as fuel.
