| 摘 要： | 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. |
