Conclusions

  1. 1.

    The dealuminization process, accomplished using acid solutions of low and medium concentration, proceeds with a retention of the starting mordenite structure.

  2. 2.

    The use of concentrated acids, even in the case of low SiO2/Al2O3 ratios, leads to a destruction of the crystalline skeleton of the mordenite.

  3. 3.

    An increase in the degree of dealuminization is preferably achieved by the technique of coupling treatment with dilute acids and intermediate heating of the samples.
