Abstract:
1. 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, deposited on a 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%; and the mole ratio between the non-noble group VIII metal(s) and the group VIB metal(s) is in the range of 0.25 to 0.45 mol/mol.
