摘要: The present invention concerns a process for the desulphurization of a gasoline cut containing sulphur-containing compounds, olefins and diolefins, comprising at least the following steps: a) fractionating the gasoline in order to recover a light gasoline cut LCN and a first heavy gasoline cut HCN; b) carrying out a first step for desulphurization of the first heavy gasoline cut HCN; c) partially condensing the first desulphurization effluent obtained from step b) in a manner such as to produce a gaseous phase essentially constituted by hydrogen and H2S and a liquid hydrocarbon phase HCN comprising dissolved H2S; d) separating the liquid hydrocarbon phase HCN into an intermediate gasoline cut MCN and a second heavy gasoline cut HHCN; e) carrying out a second step for desulphurization of the second heavy gasoline cut

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: A process for the treatment of a gasoline containing sulphur-containing compounds, olefins and diolefins, comprising the following steps: a) fractionating the gasoline in a manner such as to recover at least one intermediate gasoline cut, MCN, comprising hydrocarbons and wherein the temperature difference (ΔT) between the 5% and 95% by weight distillation points is less than 60° C.; b) desulphurizing the intermediate gasoline cut MCN alone and in the presence of a hydrodesulphurization catalyst and hydrogen in a manner such as to produce a partially desulphurized intermediate gasoline cut MCN; and c) fractionating, in a splitter, the at least partially desulphurized intermediate gasoline cut MCN which has not undergone catalytic treatment subsequent to step b), in a manner such as to recover an intermediate gasoline with low sulphur and mercaptans contents from the column head and a cut of hydrocarbons containing sulphur-containing compounds including mercaptans from the column bottom.

摘要: The present invention concerns a method for processing a petrol containing sulfur and olefin compounds, comprising the following steps: a) a step of hydrodesulfurisation in the presence of a catalyst comprising an oxide support and an active phase comprising a metal from group VIB and a metal from group VIII, b) a step of separating the H2S formed, c) a step of hydrodesulfurisation at a higher temperature than that of step a), with a hydrogen/feedstock ratio less than that of step a), and in the presence of a hydrodesulfurisation catalyst comprising an oxide support and an active phase consisting of at least one metal from group VIII, d) a step of separating the H2S formed.

摘要: A process for the treatment of a gasoline containing sulphur-containing compounds, olefins and diolefins: a) fractionating the gasoline into at least: a light gasoline cut LCN; a primary intermediate gasoline cut, MCN; and a primary heavy gasoline cut HHCN; b) desulphurizing the primary intermediate gasoline cut MCN alone producing an at least partially desulphurized primary intermediate gasoline cut MCN; c) desulphurizing the primary heavy gasoline cut HHCN alone producing an at least partially desulphurized primary heavy gasoline cut HHCN; d) sending, as a mixture, the partially desulphurized primary intermediate gasoline cut MCN and the partially desulphurized primary heavy gasoline cut HHCN to a separation column separating a gaseous stream containing hydrogen and H2S, a secondary intermediate gasoline cut MCN with low sulphur and mercaptans contents and a secondary heavy gasoline cut HHCN containing sulphur-containing compounds including recombinant mercaptans; e) desulphurizing the secondary heavy gasoline cut HHCN obtained from step d).
