<p>Selective hydrogenation of polyunsaturated compounds to monounsaturated compounds and simultaneous thickening of light saturated sulfur compounds by reaction with unsaturated compounds contained in the gasoline, is claimed, where the process is carried out in the presence of a catalyst comprising at least one metal of the group VIb and at least one non-noble metal of the group VIII deposited on a support in which the oxides of group VIb element amounts to 4-20 wt.%, and the oxides of group VIII amounts to less than 15 wt.%.
