NaY zeolite was modified with oxalic acid, and Ce(IV)Y(1) zeolite was obtained via liquid phase ion exchange between the modified NaY zeolite and cerium nitrate. The Ce(IV)Y(2) zeolite was obtained via liquid phase ion exchange between NaY zeolite and cerium nitrate. The performance of two Y zeolites [Ce(IV)Y(1) and Ce(IV)Y(2)] was compared through static selective adsorptive desulfurization of FCC gasoline at room temperature and normal pressure. The sulfur compounds and contents of the FCC gasoline were analyzed by microcoulometry and GC-SCD chromatogram. The results showed that the effect of adsorptive desulfurization of FCC gasoline achieved by Ce(IV)Y(1) zeolite was better than that of Ce(IV)Y(2) zeolite. The rate for adsorptive desulfurization of FCC gasoline by Ce(IV)Y(1) zeolite and Ce(IV)Y(2) zeolite was 85.0% and 62.4%, respectively. The Ce(IV)Y(1) zeolite could adsorb DMTs, which could not be adsorbed by Ce(IV)Y(2) zeolite. The rate of regeneration of extruded Ce(IV)Y(1)zeolite was 95.5%.
