Deep desulfurization of FCC gasoline by selective adsorption over nanosized zeolite-based adsorbents

Deep desulfurization of FCC gasoline by selective absorption was performed on various ion-exchanged nanosized Y zeolites. It was found that the metal ion as well as calcination conditions have significant influence on the absorption performance. The highest S absorption capacity was obtained on a HCuCeY sample calcined in N(2) atmosphere.
