Abstract
Nano-sized NaY zeolite had been synthesized from metakaolin by ionothermal method with microwave assisted. Its structure had been characterized by XRD, SEM, HREM, and its physicochemical properties and catalytic characteristics were studied. The results showed that the size of the product was 150–250 nm, relative crystallinity 69.16%, Si/Al ratio 5.02. Compared with conventional NaY zeolite, nano-sized zeolite composite had larger surface area and mesopore volume, better thermal stability, higher cracking activity, higher gasoline selectivity, lower coke and gas selectivity. So it has good industry application prospects.
