Desulfuration of gasoline cut by adsorption on a faujasite zeolite (I). (I) has a silicon/aluminum molar ratio of 1-10, a meso and macroporosity volume of 0.25-0.4 cm3>/g, a microporosity volume of 0.12-0.35 cm3>/g and a size of crystals less than 3 microns. Desulfuration of gasoline cut by adsorption on a faujasite zeolite (I) of formula Mx/n[(AlO2)x][(SiO2)y].zH2O. (I) has a silicon/aluminum (Si/Al) molar ratio of 1-10, a meso and macroporosity volume of 0.25-0.4 cm3>/g, a microporosity volume of 0.12-0.35 cm3>/g and a crystal size of less than 3 microns. The cation (M) is partially exchanged by cesium, with an exchange rate of 2-98%,
