摘要： The invention concerns a process for the hydrodesulphurization of gasoline cuts for the production of gasolines with a low sulphur and mercaptans content. Said process comprises at least two hydrodesulphurization steps, HDS1 and HDS2, operated in parallel on two distinct cuts of the gasoline constituting the feed. The flow rate of hydrogen in the hydrodesulphurization step HDS2 is such that the ratio between the flow rate of hydrogen and the flow rate of feed to be treated is less than 80% of the ratio of the flow rates used to desulphurize in the hydrodesulphurization step HDS1.

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.
