Abstract: The present application concerns a process for the treatment of a gasoline containing sulphur-containing compounds and olefins, with the following steps: a) a step for hydrodesulphurization of said gasoline in order to produce an effluent which is depleted in sulphur by passing the gasoline mixed with hydrogen over at least one hydrodesulphurization catalyst; b) a step for separating the partially desulphurized gasoline from the hydrogen introduced in excess as well as the H2S formed during step a); c) a catalytic step for sweetening desulphurized gasoline obtained from step b), which converts residual mercaptans into thioethers via an addition reaction with the olefins.

Abstract: The present application relates to a process for the selective hydrogenation of a gasoline which contains polyunsaturated compounds and sulphurous light compounds, the process allowing conjointly the hydrogenation of polyunsaturated compounds into mono-unsaturated compounds, increasing weight of the sulphurous light compounds by reaction with the unsaturated compounds, and maximization of the isomerization of the monounsaturated compounds comprising an external C═C double bond into their internal C═C double bond isomer, said process implementing a catalyst containing at least one group VIb metal and at least one group VIII metal deposited on a porous support.

Abstract: A process reducing sulfides R1-S-R2, with R1 and R2 methyl or ethyl, in a gasoline containing diolefins, mono-olefins and sulphur: A) contacting gasoline in mixture with a light gasoline cut recycled from C) and hydrogen in a reactor with catalyst A at least one VIb metal and at least one non noble group VIII metal on a support, producing effluent having diolefins and sulfides R1-S-R2, with R1 and R2 methyl or ethyl radicals lower than that that of the starting gasoline; B) the effluent from A) is sent into a fractionating column separating at the top a light gasoline cut containing hydrocarbons having less than 6 carbon atoms per molecule and at the bottom a heavy gasoline cut containing hydrocarbons having 6 and more than 6 carbon atoms per molecule; C) recycling a part of the light gasoline from B) to the reactor of A) with a recycle ratio 0.1 to 0.7.
