Patent ID: 7435337

Claim:
A process for intense desulphurization of a gasoline cut comprising subjecting said gasoline cut to adsorption on an adsorbent comprising a faujasite type zeolite of the general formula M x/n [(AlO 2 ) x ][(SiO 2 ) y ].zH 2 O, with a Si/Al atomic ratio in the range of 1 to 10, the cation M being partially exchanged with caesium, the degree of exchange being in the range of 2% to 98%, having a meso- and macro-porosity volume in the range of 0.25 cm 3 /g to 0.40 cm 3 /g, a micro-porosity volume in the range of 0.12 cm 3 /g to 0.35 cm 3 /g, and with a crystal size of less than 3 microns, wherein the cation M is an alkaline earth metal cation or an alkali metal cation other than caesium.
