    摘要： A process for producing a gasoline with a low sulphur content comprises: separating a sulphur-containing gasoline into a light fraction and a heavy fraction, hydrodesulphurising the light gasoline on a nickel-based catalyst, hydrodesulphurising the heavy fraction on a catalyst comprising at least one group VIII metal and/or at least one group VIB metal, and mixing the desulphurised fractions.

    摘要： The invention relates to a process of producing gasoline with a low sulphur content from a feedstock containing sulphur. This process comprises at least one step a1 of selectively hydrogenating the diolefins and acetylenic compounds, at least one separation of the gasoline (step b) obtained at step a1 into at least three fractions, at least one step c1 of treating the heavy gasoline separated at step b on a catalyst enabling the unsaturated sulphur compounds to be at least partially decomposed or hydrogenated and at least one step d to remove the sulphur and nitrogen from at least one intermediate fraction, followed by catalytic reforming.

    摘要： Production of gasolines with low sulfur contents from a starting gasoline containing sulfur-containing compounds comprising a stage a) for selective hydrogenation of non-aromatic polyunsaturated compounds present in the starting gasoline, a stage b) for increasing the molecular weight of the light sulfur-containing products that are initially present in the gasoline that enters this stage, a stage c) for alkylation of at least a portion of the sulfur-containing compounds present in the product that originates from stage b), a stage d) for fractionation of the gasoline that originates from stage c) into at least two fractions, one fraction virtually lacking in sulfur-containing compounds, whereby the other contains a larger proportion of sulfur-containing compounds (heavy gasoline), a stage e) for catalytic treatment of the heavy gasoline for transformation of sulfur-containing compounds under conditions for the at least partial decomposition of hydrogenation of these sulfur-containing compounds.
