Patent ID: 7718053

Claim:
A process comprising selectively hydrogenating a gasoline containing polyunsaturated compounds and saturated light sulphur-containing compounds, whereby the polyunsaturated compounds are hydrogenated into monounsaturated compounds and whereby, jointly, the saturated light sulphur-containing compounds are transformed into heavier compounds by reaction with the unsaturated compounds contained in the gasoline, wherein the reactions are conducted in contact with a catalyst comprising one or more metals from group VIB including at least molybdenum, and at least one non-noble metal from group VIII including at least nickel, deposited on a porous catalyst support, in which: the amount, by weight of oxide, of the group VIB metal(s) is greater than 12% by weight; the amount, by weight of oxide, of the group VIII metal(s) is less than 15% by weight; the metals in said catalyst have a degree of sulphurization of at least 60%; the volume of pores with a diameter of more than 0.05 microns is in the range 10% to 40% of the total pore volume of the catalyst; and the mole ratio between the nickel and molybdenum, Ni/Mo, is in the range of 0.2 to 0.5 mol/mol.
