A process for the treatment of a gasoline containing sulfur compounds and olefins includes the following stages:

Method for producing gasoline with low sulphur and mercaptan content

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 HS 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 HS formed.

Method for producing a petrol with low sulfur and mercaptans content

The present invention relates to a method for treating a pyrolysis gasoline C5containing monoolefinic, diolefinic and sulfur hydrocarbons, comprising at least, and in any order: a) a step of hydrotreating the pyrolysis gasoline or a hydrocarbon fraction C6originating from the pyrolysis gasoline, in the presence of hydrogen and at least one hydrotreatment catalyst at a temperature ranging between 220 and 380&#xb0; 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 C5and 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.

Method for treating a pyrolysis gasoline

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 HS and a liquid hydrocarbon phase HCN of dissolved HS; (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.
