Abstract

Characterization of MCM-22 was curried out by X-ray diffraction (XRD), scanning electron microscopy (SEM), thermal analysis (TG~DTA) and nuclear magnetic resonance (NMR). TGA-DTA and NMR studies indicate a strong interaction of the template with the zeolite framework. Adsorption studies indicate the internal void volume to be intermediate between the volumes of zeolite beta and ZSM-12. In catalytic reactions such as the isomerization of m-xylene, aromatization of n-hexane and transformation of methanol to hydrocarbons, the zeolite behaves like a large-pore zeolite, even though recent research has established that it is a medium-pore zeolite.
