N2 - Structure stabilized Y (SSY) zeolite with high rare earth content was prepared by following the RE3+-exchange of NaY with a SiCl 4 treatment. Due to RE3+ cation location in the zeolite lattice, migrating direction and presence state could be well controlled in processing, the SSY possesses the following characteristics: initial unit cell constant a0= 2.450-2.458nm, equilibrium unit cell size >2.435nm, RE2O3 content could be adjusted within 6-14wt%, sodium oxide content less than 1.70 wt%, and a differential thermal collapsed temperature, DTA >1000°C. Research results indicate that the SSY with an improved heavy oil conversion, a better coke selectivity and a higher hydrogen transfer activity and stability is suitable as an active component of cracking catalyst for clean gasoline production.
