    Abstract

    This chapter reviews desilication and the effect of desilication on the zeolite framework. It also reviews the mechanism of desilication, and its potential applications. Silicalite-1 is the all-silica version of ZSM-5. The desilication behavior of all silica zeolite would provide great insight to understand the progress of desilication and dissolution of the siliceous part of zeolite. Desilicated zeolite can function as a host not only for small components such as Fe(III) metal cations but also for larger macromolecules such as enzymes. The chapter describes the changes occurring throughout the alkali (alkaline) treatment of zeolites. ZSM-5 and other medium-pore, small-pore, and low-dimensional microporous zeolites are impacted by this treatment, resulting in significant improvement of diffusivity throughout their intrinsic microporous structure.
