Abstract:
A process for producing a gasoline with a low sulphur content, in which said process comprises the stages of:separating a gasoline containing sulphur into a light fraction and a heavy fraction, the cut point being selected so that the light fraction has a higher olefin content than the heavy fraction; hydrodesulphurising the light fraction on a nickel-based catalyst under conditions limiting olefin conversion, wherein the nickel-based catalyst consists essentially of nickel as the catalytically active metal; hydrodesulphurising the heavy fraction on a catalyst comprising at least one group VIII metal selected from the group consisting of iron, ruthenium, osmium, cobalt, rhodium, iridium, palladium, platinum, and/or at least one group VIB metal, and; mixing the resultant desulphurised light and heavy fractions.
