CHANGES IN THE ACIDIC PROPERTIES OF THE ZEOLITE H-ZSM-11 UNDER THE INFLUENCE OF HYDROGEN AND WATER

The nature of the effect of hydrogen and water on the spectrum of acidity of H-ZSM-11 zeolite has been studied. An explanation of the observed changes is proposed and a prognosis has been made on the relative effect of transformation of the functional groups of the surface on the catalytic properties of H-ZSM-11 in various reactions of acid type.
