Abstract： NaY zeolites with nanosize and normal size were successfully synthesized through different ways.The X-ray diffraction and TEM results indicated that the crystal zeolite product had an average size under 100 nm.Fluid catalytic cracking(FCC) catalysts was prepared respectively from the two zeolites.FCC test results showed that compared with catalyst containing conventionally hydrothermal synthesized NaY zeolite,catalyst containing nanosized zeolite exhibited good big molecule cracking performance and excellent selectivity.
