中文摘要：

以Na20—3SiO2-AI2O2地质聚合物为载体和养分来源，通过水热合成法将其原位转化为自支撑八面沸石膜。利用XRD、SEM、BET、万能压力试验机等表征手段，研究了膜材料的力学性能、微观结构、相组成及表面化学性质。实验结果表明，膜材料表面晶体致密连续，晶粒尺寸均匀分布在500—600nm；BET表面积为63．31m。／g，抗压强度为19．6MPa，平均孔径为14．36nm；沸石晶体最初是在表面及介孔周围生成的。以醇水体系脱水为分离性能指标的研究表明，在进料温度为50℃，进料组成为70wt％的醇水体系中，八面沸石膜乙醇渗透通量和分离因子可分别达到1．41kg／（h·m。）和16．8。说明利用地质聚合物合成的自支撑八面沸石膜能够有效分离醇水体系。

英文摘要：

Self-supporting faujasite zeolite membranes were synthesized using Na20-3SiO2 -A1203 geoploymers as supporters and source of nutrients by in-situ hydrothermal growth method. The sur- face properties, microstructure, phase composition and compressive strength were analyzed by X-ray diffraction, SEM, BET and Universal pressure testing machine. The results showed that the surface of the membrane is continuous and its grain size distribution is between 500 -600 nm; BET surface area is 63.31 m2/g; the compressive strength is 19.6 MPa and average pore diameter is 14. 36 nm. Zeolite crystals originally generated in the surface and mesoporous. The investigation of its separation performance in alcohol/water system showed that the permeate flux and separation factor can reach 1.41 kg/（h ~ m2）and 16.8 in alcohol/water system as the feed temperature is 50 C and the con- centration of alcohol in 70 wt%, demonstrating that the self-supporting faujasite zeolite membrane can effectively separate alcohol from water.
