摘要
本文从超稳Y分子筛的制备与改性两个方面综述了超稳Y分子筛(USY分子筛)的研究进展,对改性的超稳Y分子筛的二次孔体积、比表面积、水热稳定性、酸量和酸强度等方面进行总结,并对USY分子筛改性研究的重点及发展方向进行了展望。
The research progress on Ultra-stable Y（USY） zeolites was reviewed in this article, consisting of preparation and modification technology. The modification of USY zeolites of secondary pore volume, specific surface area, hydrothermal stability, acidity and strength of acid and other aspects were summarized. The development trends of the modification USY zeolites was forecasted in the future.
