The　purpose　of　this　study　is　to　evaluate　the　dehydration　kinetics　of　MxNa96-x-LSX　(M　=　L+　Ca2+　and　Ag+)　zeolites　and　assess　their　potential　for　N-2/O-2　adsorption　and　selectivity　using　ideal　adsorbed　solution　theory.　In　order　to　achieve　our　objective,　MxNa96-x-LSX　(M　=　Li+,　Ca2+,　and　Ag+)　zeolites　were　prepared　via　conventional　ion　exchange　methods　from　Na-LSX　zeolite.　Meanwhile,　their　structural　and　textural　properties　were　characterized　by　N-2　adsorption-desorption,　TG-DTG,　ICP-OES,　XRD,　FT-IR,　EDS,　elemental　mapping　and　SEM　techniques.　The　kinetics　(activation　energy,　pre-exponential　factor,　and　most　probable　mechanism/model)　of　dehydration　process　were　investigated　via　Kissinger,　Flynn-Wall-Ozawa　and　Coats-Redfern　methods.　The　results　show　a　strong　dependence　on　the　choice　of　mechanism　function,　which　can　help　in　proposing　the　best　relevant　kinetic　model.　Moreover,　the　results　further　reveal　that　Li+　and　Ca2+　ions　(which　are　inexpensive)　in　Li-LSX　and　Ca-LSX　fill　the　low-energy　sites　SI,　SI＇,　SII,　and　SII＇　first　and　then　SII　and　SIII＇　sites.　Li-LSX　and　Ca-LSX　hold　comparative　advantages,　which　suggest　that　they　would　be　the　most　promising　adsorbents　for　air　separation　and　pure　oxygen　production　by　pressure　swing　adsorption.　However,　Ag-LSX　presents　superior　performance　at　relatively　low　pressures.　Therefore,　the　quantitative　evaluation　of　kinetic　parameters　of　dehydration　is　necessary　to　provide　the　theoretical　principles　in　understanding　N-2　and　O-2　adsorption　phenomena.
