Conclusions

  1. 1.

    L zeolite exhibits weak selectivity for NH4+ cations which decreases as the degree of ion exchange increases in substitution of potassium cations with ammonia ions.

     
  2. 2.

    Only L zeolites with a degree of decationization above 50% exhibit catalytic activity in transformation of o-xylene.

     
  3. 3.

    Isomerization of xylenes on L zeolites primarily takes place by means of intramolecular transformations.
