摘要： The invention concerns a process for hydrodesulphurizing a gasoline containing less than 0.1% by weight of sulphur derived from a catalytic cracking unit or other conversion units, said process comprising at least one hydrodesulphurization reactor using a bimetallic catalyst operating at a HSV in the range 0.1 h−1 to 20 h−1, a temperature in the range 220° C. to 350° C. and a pressure in the range 0.1 MPa to 5 MPa, and comprising recycling a fraction of the desulphurized gasoline to the inlet to the hydrodesulphurization reactor with a recycle ratio in the range 0.1 to 3 times the flow rate of the gasoline to be desulphurized.

摘要： The invention concerns a process for desulphurizing gasoline comprising a step for fractionating said gasoline under conditions in which a light fraction comprising the lightest thiophene compounds such as thiophene or methylthiophenes and a heavy fraction concentrating the heaviest aromatic sulphur-containing compounds are obtained. Said heavy fraction is treated by hydrodesulphurization, while the light fraction is brought into contact with a solid adsorbant to eliminate at least a portion of said light thiophene compounds.

摘要： A process for reducing the quantity of sulphur present in a hydrocarbon feed such as a gasoline or a gas oil, comprises: a) bringing said feed containing sulphur-containing compounds into contact with an adsorbent having a selectivity for sulphur-containing compounds under conditions for producing, at the outlet from the contact zone, a desulphurized effluent which is collected, said adsorption being carried out in the liquid phase or in the gas phase; b) gas phase desorption of the sulphur-containing compounds present on said adsorbent using a hydrogen-containing gaseous fluid derived from a hydrodesulphurisation zone to obtain a gaseous effluent comprising hydrogen and desorbed sulphur-containing compounds; c) sending the gaseous effluent from step b) to said hydrodesulphurization zone and desulphurizing it therein.
