Conclusions

  1. 1.

    New structural hydroxyl groups are not formed during the elimination of small amounts of Al from type Y zeolites.

  2. 2.

    Extensive elimination of aluminum from such zeolites leads to a marked increase of the concentration of weakly acidic hydroxyl groups.

  3. 3.

    The Y-type zeolite framework is partially retained in x-ray amorphous samples with 104 SiO2/Al2O3 ratio.
