The invention relates to a process for the production of gasoline with a low sulfur content that comprises at least the following stages:n a1) at least a selective hydrogenation of diolefins, a2) optionally at least one stage that is aimed at increasing the molecular weight of the light sulfur-containing products that are present in the gasoline, b) at least one separation of the gasoline that is obtained in stage a1 or a2 into two fractions: light gasoline and heavy gasoline, c) at least one treatment with heavy gasoline that is separated in stage b on a catalyst that makes it possible to decompose or to hydrogenate at least partially the unsaturated sulfur-containing compounds, d) at least one treatment of the heavy gasoline that is obtained in stage c, without eliminating the H2S that is formed during this stage, on a catalyst that makes it possible to decompose the sulfur-containing compounds and more preferably the linear and/or cyclic saturated compounds. |
