摘要： 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.

摘要： 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.

摘要： This invention relates to a method for reducing the content of sulfide-type compounds of formula R1-S—R2, with R1 and R2 selected from among the methyl (CH3) and ethyl (C2H5) radicals, of a gasoline that contains diolefins, monoolefins, and sulfur. The method implements a first catalytic step for selective hydrogenation of diolefins at a temperature of between 60° C. and 150° C. and then a step for heating the effluent that is obtained from the first step with a temperature difference ΔT of between 10° C. and 100° C. and a second catalytic step on the effluent that is heated in such a way as to produce an effluent that has a content of sulfide-type compounds of formula R1-S—R2, with R1 and R2 selected from among the methyl (CH3) and ethyl (C2H5) radicals, lower than that of the starting gasoline.

摘要： A process for the concomitant production of at least two hydrocarbon cuts with low sulphur contents from a mixture of hydrocarbons having a total sulphur content in the range 30 to 10000 ppm by weight, by a) hydrodesulphurization in the presence of hydrogen and a hydrodesulphurization catalyst; b) separating hydrogen sulphide from the partially desulphurized effluent obtained from a); c) hydrodesulphurization of the partially desulphurized mixture obtained from b) in the presence of hydrogen and a hydrodesulphurization catalyst, the temperature of the second hydrodesulphurization being higher than that of the first hydrodesulphurization; d) fractionating the desulphurized mixture obtained in c) into at least two desulphurized hydrocarbon cuts.
