Patent ID: 8034233

Claim:
A process for hydrodesulphurizing a gasoline containing less than 0.1% by weight of sulphur derived from a catalytic cracking unit having an inlet and an outlet, or from other conversion units, said process comprising in a hydrodesulfuration reactor conducting at least one hydrodesulphurization reaction of said gasoline in contact with a bimetallic catalyst, operating at an hourly superficial velocity (HSV) in the range of 0.5 h −1 to 8 h −1 , a temperature in the range of 280° C. to 350° C. and a pressure in the range of 1 MPa to 3 MPa, and recycling a first fraction of the desulphurized gasoline from the outlet to the inlet of the hydrodesulphurization reactor with a recycle ratio in the range of 0.2 to 2 times the flow rate of the gasoline to be desulphurized.
