Abstract (en)
The hydrodesulfurization of a gasoline containing less than 0.1 wt.% sulfur comprises hydrodesulfurizing the gasoline in contact with a bimetallic catalyst in a hydrodesulfuration reactor (12) operating at an hourly superficial velocity (HSV) of 0.1-20 h -1>, at 220-350[deg]C and 0.1-5 MPa; and recycling a first fraction of the desulfurized gasoline from an outlet to an inlet of the reactor with a recycle ratio of 0.1-3 times the flow rate of the gasoline to be desulfurized.
