Abstract

The volumetric method has been used to study the adsorption properties of zeolites CaA, NaX, and CaNaA; adsorption isotherms and adsorption capacities for nitrogen, oxygen, and air have been obtained. The nitrogen/oxygen selectivity values of zeolites have been determined. The experimental adsorption isotherm of air has been compared with the adsorption isotherm obtained for the pure components. The experiments have revealed that the most promising zeolite for use in a membrane–adsorption oxygen concentrator is zeolite CaNaA.

NaX，CaA和CaNaA沸石在空气成分分离中的吸附性能研究

摘要

体积法已被用于研究CaA，NaX和CaNaA沸石的吸附性能。获得了吸附等温线以及对氮，氧和空气的吸附能力。已经确定了沸石的氮/氧选择性值。将空气的实验吸附等温线与纯组分的吸附等温线进行了比较。实验表明，用于膜吸附氧气浓缩器的最有前景的沸石是CaNaA沸石。
