Abstract

The thermal stabilities of hydrogen faujasites and mordenites with different Si/al ratios are reported. The temperature fields are outlined which characterize the thermal resistance of the lattice, framework Al, hydroxyl coverage, and the active sites. By choosing the proper conditions for activation of hydrogen zeolites, it is possible to induce the release of Al from the framework and inthis way to promote the formation of strong acid sites and enhance the catalytic activity.
