Conclusions

  1. 1.

    The mobility of surface hydrogen increases in passing from faujasite to mordenite structure, and increasing the degree of surface dehydroxylation.

  2. 2.

    The increase in the zeolite structure stability observed in going from X to Y to mordenite is accompanied by an increase in the OH group thermal stability. Breakdown of the mordenite crystal structure leads to a reduction in the OH group concentration.
