Abstract
For desulfurization of a hydrocarbon-containing feedstock, at least one stage for selective hydrogenation of diolefins present in the initial hydrocarbon feedstock, in the presence of a catalyst of group VIII of the period table, and a stage for extraction by a solvent of the resultant hydrogenated fraction under conditions that provide at least two fractions:
