Table 2 illustrates the comparison of catalytic properties between the aged samples of molecular sieves prepared by two sodium removal methods.As shown in Table2,compared with the molecular sieve prepared by ammonium ion-exchange,the gasoline yield of the REUSY molecular sieve prepared by bipolar membrane electrodialysis increases slightly,and the coke yield decreases,but the catalytic properties of the molecular sieved prepared by two methods are still basically equivalent.With respect to ZSM-5 molecular sieve,the catalytic properties of the molecular sieves prepared by the electrodialysis and ammonium ion-exchange methods are fundamentally consistent.
