the Na-Y type molecular sieve is a sodium type aluminosilicate crystal having a large specific surface area. Y molecular sieve is widely used as the catalytic cracking catalyst as acid activation component, and can also be used in petroleum refining and petrochemical catalytic processes such as adsorbent, hydrocracking, alkylation, hydrodewaxing, diesel pour point depressing.
