    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.

    摘要: The invention relates to a process for the production of gasoline with a low sulfur content that comprises at least the following stages: 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.
