ID#　233717　ETS-4　had　attracted　more　and　more　attentions　for　many　researchers　because　of　its　potential　properties　in　adsorption,　gas　separation,　and　catalysis,　which　has　octahedral-tetrahedral　structure　with　the　potential　properties　that　were　different　from　the　conventional　zeolite　materials[1].　The　preparation　and　crystallization　of　ETS-4　with　small　pores　had　been　reported　by　many　researchers[2-4].　In　this　paper,　titanosilicate　ETS-4　sieves　with　the　Sr　and　Ni　modification　were　prepared　by　hydrotherrmal　method　using　the　titanium　trichloride　and　tetraethoxysilane　as　the　precursors.　The　properties　and　morphology　of　the　materials　were　also　characterized　by　XRD,　SEM　and　PSA　techniques.　The　Sr　and　Ni　doping　could　improve　the　N2　and　CH4　adsorption　capacity　of　ETS-4.　The　N2　and　CH4　adsorbance　increased　in　the　pressurization　process　for　ETS-4-Sr　and　ETS-4-Ni,　but　no　significant　change　in　N2　and　CH4　adsorbance　with　the　pressure　increasing　was　observed　over　the　ETS-4　sample.　At　the　pressure　of　1200　mmHg,　the　N2　adsorbances　for　ETS-4-Sr　and　ETS-4-Ni　were　4.2　and　3.9　times　as　that　of　ETS-4　sieve,　respectively.　Summary,　the　metal　ion　doping　(Sr2+　and　Ni2+)　can　improve　the　adsorption　performance　of　ETS-4　greatly.　©　2011　AIChE.　All　rights　reserved.
