    摘要: This invention comprises USY zeolite prepared by treating a USY zeolite under hydrothermal conditions after forming the USY zeolite from heat treating ammonium exchanged zeolite Y, e g, by calcination. When this invention is used in a FCC catalyst, a significant improvement of activity and selectivity in the fluid catalytic cracking (FCC) performance is observed, compared to FCC catalysts containing conventional USY zeolite. The process used to make the invention is efficient and comprises treating the USY zeolite in an exchange bath under the aforementioned hydrothermal conditions. The surface of the resulting USY zeolite has a molar ratio of alumina to silica that is higher than that seen in the bulk USY zeolite and has a unique structure as viewed by SEM and TEM.
