Abstract: 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.

Abstract: A process for the desulphurization of a gasoline cut containing sulphur-containing compounds, olefins and diolefins, involving (a) fractionating the gasoline in order to recover a light gasoline cut LCN and a first heavy gasoline cut HCN; (b) desulphurization of the first heavy gasoline cut HCN; (c) partially condensing desulphurization effluent obtained from b) in a manner such as to produce a gaseous phase of hydrogen and H2S and a liquid hydrocarbon phase HCN of 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 desulphurization of the second heavy gasoline cut HHCN.

Abstract: A process for the treatment of a gasoline containing sulfur compounds and olefins includes the following stages:
a) hydrodesulfurization in the presence of a catalyst having an oxide support and an active phase having a metal from group VIB and a metal from group VIII,
b) hydrodesulfurization at a higher temperature than that of stage a) and in the presence of a catalyst having an oxide support and an active phase with at least one metal from group VIII,
c) separation of H2S formed,
d) hydrodesulfurization at a low hydrogen/feedstock ratio and in the presence of a hydrodesulfurization catalyst having an oxide support and an active phase having a metal from group VIB and a metal from group VIII or an active phase with at least one metal from group VIII, and
e) further separation of H2S formed.-

Abstract: The present invention relates to a method for treating a pyrolysis gasoline C5+ containing monoolefinic, diolefinic and sulfur hydrocarbons, comprising at least, and in any order: a) a step of hydrotreating the pyrolysis gasoline or a hydrocarbon fraction C6+ originating from the pyrolysis gasoline, in the presence of hydrogen and at least one hydrotreatment catalyst at a temperature ranging between 220 and 380° C. so as to produce a hydrotreated effluent; b) a step of separating the pyrolysis gasoline or the hydrotreated effluent originating from step a) when said step is completed before step b), into a separation column for separating into a top hydrocarbon fraction C5− and a bottom hydrocarbon fraction C6+, said separation column comprising a reboiling section including two heat exchangers, at least one of the two exchangers being configured to perform a heat exchange with a portion of the bottom fraction that is recycled in the column via the reboiling section. According to the invention, one of the two heat exchangers of the reboiling section is supplied with at least one portion of the hydrotreated effluent so as to supply part of the heat required to operate the reboiling section.

Abstract: 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).
