21 Claims

1. A process for the hydrodesulfurization of a sulfur-containing olefinic gasoline cut, comprising:

bringing said gasoline cut, hydrogen and a catalyst into contact, and carrying out said hydrodesulfurization process 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 the catalyst, of between 1 and 10 h-1 and a hydrogen/gasoline cut ratio by volume of between 100 and 600 SI/l,

wherein said catalyst comprises an alumina support obtained by dehydration of an aluminum hydroxide or oxyhydroxide at a temperature of between 400 and 1200° C. and for a period of time of between 0.1 second and 5 seconds, at least one metal from group VIb, at least one metal from group VIII, and phosphorus, the molar ratio of the phosphorus to the metal from group VIb being between 0.2 and 0.35.
