摘要
1实验部分1.1试剂及样品环己烷、正己烷和无水乙醇(分析纯)均为沈阳化学试剂厂生产。去离子水由本校去离子水室提供。沸石膜样品的合成由本实验室完成[1],分别为NaZSM-5和高硅ZSM-5(Si/Al=1000)。1.2重量法沸石膜厚度测定在CAHN...
The framework and thickness of synthesized ZSM 5 membranes were characterized using static and dynamic adsorption methods. It is shown that the adsorptive properties of the membranes are the same as ZSM 5 zeolite, the average thickness of the membranes was 13 μm calculated from the adsorptive ability, which matched very well with the result measured by scanning electron micrograph. The results also shown that zeolite membranes have greated adsorptive ability than zeolite powders. The high Si/Al rate zeolite membranes have selective ability on ethanol/water, and this interpreted the separation of ethanol water mixtures with the membranes.
