摘要： 采用二次生长法，在无有机模板剂的条件下于a-Al2O3载体上制备丝光沸石膜. 所制丝光沸石膜用于四氢呋喃(THF)水溶液脱水浓缩，考察了操作温度、THF浓度对其渗透汽化性能的影响. 结果表明，在操作温度为60℃、THF浓度为90%(w)时，丝光沸石膜的渗透通量和分离因数分别为0.35 kg/(m2×h)和9233，渗透液水含量达99.907%(w). THF浓度在75%~97%范围内，渗透液的水含量均在99.6%以上. 对THF浓度为97.066%(w)的模拟制药废液脱水37 h后，THF浓度达99.640%.

Abstract: The secondary growth method was used to prepare mordenite zeolite membrane on a-Al2O3 support without using any organic templating agent. The synthesized membrane was applied in the dehydration concentration of tetrahydrofuran (THF). The effects of operating temperature and THF concentration on the pervaporation performance were investigated. The results indicated that at 60℃ and THF concentration of 90%(w), the permeate flux and separation factor of the membrane reached 0.350 kg/(m2·h) and 9233, respectively. In the THF concentration range from 75% to 97%, the water content in permeate liquid was over 99.6%(w). After concentration of the simulated pharmaceutical waste liquor [97.066%(w) THF/water solution] for 37 h, the THF concentration reached 99.640%(w).
