摘要: 通过对分子筛的改性,构造各种类型、各种强度的能垒。测定在不同温度和压力下,吸附质在分子筛
上的吸附扩散性能。结果表明,随CuO 质量分数的增加,乙烯在CuO/HMor上的吸附量先增加后减少。随Cs+ 质
量分数的增加,乙烯在Cs+/HMor上的总吸附量增加,低频吸附量减少,高频吸附量增加。把频率响应法和智能重
量分析法测得的吸附量进行比对,阐述了用频率响应方法研究吸附机理的可行性。

Abstract:  

The various type and strength energy barrier was structured by the modified   molecular sieve. The adsorption and diffusivity performance of object adsorption molecular on the chose absorbent under the different temperature and pressure were determined. The results show that with the CuO mass fraction increase, the adsorptive capacity of ethylene in CuO/HMor first increases and then decreases. With the Cs+ mass fraction increase, total adsorptive capacity of ethylene in Cs+/HMor increases, high frequency adsorptive capacity increases, low frequency adsorptive capacity decreases. Compared adsorption capacity derived from the frequency response spectra with adsorption capacity derived from the intelligent gravimetric analyser, consequently adsorption mechanism which was explanded by frequency response method is reliability.
