Abstract: The ratio and kind of template agent were investigated for the preparation of ZSM-5 zeolite membranes using the two-steps hydrothermal synthesis method. The membranes were characterized with X-ray diffraction (XRD) and scanning electron microscope (SEM). Desulfurization experiments were conducted in model gasoline. With increasing ratio of TPAOH，membrane particle shape gradually became regular，but an overly high ratio of TPAOH could make membrane particles irregular. Membrane structure was the most regular and thiophene removal was the best when ZSM-5 zeolite membrane was prepared with TPAOH ratio of 30. Membranes prepared by double template agent of “TPAOH+absolute ethylalcohol” could achieve the highest removal of sulfides. The membrane was used to remove bicomponent model gasoline，and removal of bicomponent sulfides was better than removal of sulfides in single component model gasoline.

摘要： 采用二次水热合成法，考察了模板剂的配比和种类对ZSM-5分子筛膜合成的影响，用X线衍射光谱仪（XRD）和扫描电子显微镜（SEM）进行表征，并用模拟汽油进行脱硫实验。结果表明：改变模板剂的配比时，随着四丙基氢氧化铵（TPAOH）的增加，膜颗粒形状逐渐变为规整，但过高的TPAOH配比会使膜颗粒变为不规整，TPAOH配比为30制得的ZSM-5分子筛膜结构最为规整且对噻吩（TP）的脱除效果最好；改变模板剂的种类时，“TPAOH+乙醇”的双模板剂制得的膜脱硫效果最好，进一步对双组分模拟汽油进行脱除时，可以得出双组分硫化物被脱除的效果好于单组分的模拟汽油。
