Conclusions

  1. 1.

    The principal factors that determine the degree of dealumination during acid treatment are the temperature of heating the hydrogen (ammonium) form, the amount of Na2O in it, and also the acid concentration.

     
  2. 2.

    A coupling of the acid treatments with a heating of the hydrogen (ammonium) form at various temperatures represents a convenient method for the preparation of mordenite samples in a wide range of SiO2 /A12O3 ratios.
