摘要：

The　hybrid　(Li,　Ca)-LSX　zeolites　were　prepared　via　ion　exchange　method　with　Na-LSX　zeolite　as　starting　material,　and　their　structural　and　textural　characteristics　were　investigated　by　using　ICP-AES,　TG　and　N2　adsorption-desorption　techniques.　The　results　showed　that　the　order　from　easy　to　difficult　for　cation　exchange　was　Ca2+,　Li+,　Na+.　The　main　factors　to　affect　the　N2　adsorption　ability　of　LSX　were　the　size　of　the　cation　and　its　distribution　in　LSX　and　the　binding　force　of　cation　with　N2　molecules,　which　affected　first　the　water　absorbing　capacity　and　textural　properties,　then　the　N2　adsorption　capacity　of　LSX.
