Conclusions

  1. 1.

    In the acid treatment of mordenite, the aluminum removal takes place first in the surface layer, and as a result, a nonuniform distribution of Al is observed in the dealuminized samples.

  2. 2.

    The catalytic conversion of alkylaromatic compounds take place in the large channels of the mordenite, close to the surface.

  3. 3.

    In mordenites with a low content of aluminum, molecular-sieve selectivity is manifested in the primary formation of unsymmetrical trimethylbenzenes in the products from the disproportionation of o-xylene.
