中文摘要：

以 NaY 和 HY 分子筛为研究对象，运用 N2吸附表征两种 Y 型分子筛的物化性能；以苯为芳烃的模型化合物，采用频率响应技术（FR）和智能重量分析技术（IGA）相结合的方法，研究了苯在 Y 型分子筛上的吸附扩散行为。研究发现，苯与 NaY 分子筛骨架中 Na＋的相互作用大于苯与 HY 分子筛中 B 酸的相互作用，并且高温有利于苯在分子筛上的扩散。FR 技术能够有效的识别客体分子在分子筛微孔孔道内发生的不同传质过程，并能识别出作用力的强弱，是研究微孔材料动力学的有效方法和手段。

英文摘要：

The physical and chemical properties of NaY and HY zeolites were characterized by N2 adsorption.The adsorption and diffusion behavior of benzene on NaY and HY zeolites were studied by using Frequency Response （FR）and Intelligent Gravimetric Analysers （IGA ）technique.These results indicate that the interaction of benzene on NaY zeolite with the Na＋ in the framework is greater than the interaction of benzene on HY zeolite with the B acid.In addition,the higher temperature is conducive to the spread of benzene in the zeolite.Different mass transfer processes and the strength of the force of the molecules in the microporous of these zeolites can be validly identified by FR technique.It is an effective way to study the dynamics of microporous materials.
