Abstract
The scope of this chapter is to present a review of relatively recent research work on operations and processes that involve the interaction of natural zeolites with organic vapors or gases, in a simple and comprehensive way. The time horizon for the bibliographic search was set at 20 years back. Modified natural zeolites have also been included, since a modification step (most usually by ion-exchange) of the naturally occurring materials is usually considered essential prior to any use.
Keywords: Natural zeolite, organic vapor, organic gas, adsorption, adsorption heat, isotherm, separation, purification, selectivity, diffusion, accessibility, gas chromatography, catalysis, zeolite modification, binary adsorption, pore engineering, dealumination, henry, langmuir, microporous, mesoporous.
