Claim:
1. A process for treating a gasoline comprising diolefins, olefins, and sulfur-containing compounds including mercaptans, consisting of a stage for treating gasoline in the presence of hydrogen in a distillation column ( 2 ) comprising at least one reaction zone ( 3 ) including at least one catalyst, with the catalyst being in sulfide form and comprising a substrate that consists of gamma-alumina or delta-alumina with a specific surface area of between 70 m 2 /g and 350 m 2 /g, a content by weight of oxide of the element of group VIb of between 1 and 30% by weight relative to the total weight of the catalyst, a content by weight of oxide of the element of group VIII of between 1 and 30% by weight relative to the total weight of the catalyst, a sulfurization rate of the metals that constitute said catalyst that is at least equal to 60%, a molar ratio between the metal of group VIII and the metal of group VIb of between 0.6 and 3 mol/mol, in which: gasoline is injected into the distillation column at a level located below the reaction zone ( concurrently the gasoline that distills at the top of the catalytic column is brought into contact with the catalyst of the reaction zone ( in which the distillation column is configured for operating as a depentanizer in such a way as to provide a light gasoline that has at most 5 carbon atoms or in which the distillation column is configured for operating as a dehexanizer in such a way as to provide a light gasoline that has at most 6 carbon atoms.
