Abstract
The invention relates to a process for the hydrodesulfurization of a sulfur-containing olefinic gasoline cut in which said gasoline cut, hydrogen and a rejuvenated catalyst are brought into contact, said hydrodesulfurization process being carried out at a temperature of between 200° C. and 400° C., a total pressure of between 1 and 3 MPa, an hourly space velocity, defined as being the flow rate by volume of feedstock relative to the volume of catalyst, of between 1 and 10 h−1 and a hydrogen/gasoline feedstock ratio by volume of between 100 and 1200 Sl/l, said rejuvenated catalyst resulting from a hydrotreating process and comprises at least one metal from group VIII, at least one metal from group VIb, an oxide support and at least one organic compound containing oxygen and/or nitrogen and/or sulfur.
