    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.

    摘要： In a catalyst process involving a conversion reaction for organic compounds, e.g. hydrogenations, the catalyst contains at least one support and at least one metal, and is characterized in that it has particles of an average size greater than approximately 1 nm, and more than 80% of particles, the size of which is comprised in the range D±(D.0.2) where D represents the average size of the particles. The catalyst is prepared in a colloidal suspension, in aqueous phase, of the metal oxide or metals to be supported, then depositing this suspension on a support, and optionally reducing the oxide thus supported.
