The　clinoptilolites　(CPs)　with　high　purity　were　prepared　via　structure　directing　agent　(SDA)　method　combining　with　hydrothermal　method　using　silica　sol　as　the　silica　source　and　aluminum　hydroxide　as　the　aluminum　source.　Their　structural　features　were　characterized　by　X-ray　diffraction　(XRD)　patterns,　Fourier　transform　infrared　(FT-IR)　spectra,　thermal　gravimetric　(TG)　analysis,　scanning　electron　micrograph　(SEM)　images,　Si-29　nuclear　magnetic　resonance　(NMR)　profiles.　The　effects　of　additive　amount　and　aging　time　of　used　SDA,　as　well　as　synthetic　parameters　such　as　crystallization　temperature　and　crystallization　time　on　their　structure　and　performance　were　emphasized.　Particularly,　the　activation　energies　of　their　crystallization　kinetics　at　different　stages　of　induction　period　and　growth　period　were　calculated　on　the　basis　of　Arrhenius　equation.　The　results　demonstrated　that　the　obtained　CPs　presented　the　highest　relative　crystallinity　when　the　additive　amount　of　used　SDA　was　1　mL　at　aging　periods　of　2　d,　otherwise,　their　relative　crystallinity　degree　was　low　due　to　existences　of　a　large　number　of　heterocrystal　impurities.　Particularly,　the　apparent　activation　energy　values　for　induction　(E-n)　and　growth　(E-g)　profile　were　calculated　by　the　Arrhenius　equation.　The　E-n　value　(86.46　kJ/mol)　of　induction　period　was　much　higher　than　that　E-g　value　(9.64　kJ/mol)　of　growth　stage,　suggesting　that　the　induction　period　was　the　main　controlling　step　during　the　synthetic　CP.　Finally,　the　synthetic　CP　was　employed　to　preliminarily　assess　its　performances　for　CH4/N-2　separation.　These　demonstrations　provide　a　promising　method　for　the　synthesis　of　CPs.
