在多孔陶瓷载体上制备过渡层,再以水热法合成出ZSM—5型沸石膜.经扫描电镜测定,膜厚12μm,过渡层厚13.8μm.将ZSM—5沸石膜用于乙醇水渗透蒸发分离,分离因数为15,这时其渗透通量为0.46kg/m2·h.
Zeolites with less than 10A pores are desirable membrane materials, due to their crystallinity, resistance to high temperatUre, and chemical inertness. In this paper, the synthesis and some properties of.pure ZSM-5 zeolite membrane on the porous support b
