Patent ID: 7744748

Claim:
A process for reducing the quantity of sulphur present in a gasoline feed, comprising the following steps: a) bringing said gasoline feed containing sulphur-containing compounds into contact with an adsorbant 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 gas phase; b) gas phase desorption of the sulphur-containing compounds present on said adsorbant using a gaseous fluid comprising hydrogen and deriving from a hydrodesulphurisation zone to obtain a gaseous effluent comprising desorbed sulphur-containing compounds and the gaseous fluid comprising hydrogen; c) sending the effluent from step b) to said hydrodesulphurization zone and desulphurizing it therein.
