频率响应法研究苯在Y型分子筛上的吸附扩散行为
Adsorption and Diffusion Behavior of Benzene on Y Zeolite with Frequency Response Method
摘要
Abstract
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.关键词
