The influence of hydrogen and water on the spectrum of acidity of zeolite H-ZSM-11 was studied. A possi- ble explanation of the effect was discussed. The forecast concerning the influence of transformation of the surface functional groups on catalytic properties of H-ZSM-11 in various reactions of the acid type was made.

Key word zeolite, acidity, catalysis, hydrogen, water.
