Zeolites Commercial Applications –A Review

Abstract

Zeolites can be classified into two general categories: normal and manufactured zeolites. Normal zeolites are composed of volcanic and sedimentary rocks such as Chabazite, clinoptilolite, and mordenite.These are commonly used as catalysts in the petrochemical industry for fluid catalytic cracking and hydrocracking, among other processes.Small-space containment of molecules by zeolites results in modifications to both structure and reactivity. These are microporous, three-dimensional crystalline solids of aluminium silicate and are used in ion exchange for the purification of hard water to soft water. In aqueous medium, the hydrated cations in zeolite can readily exchange with the other cations. These applications can be seen in water softening devices and zeolites are used in soaps, detergents. it also used to remove radioactive ions from the polluted water. Zeolites are alumino silicates that belong to the "molecular sieve" family of microscopic porous solids.
