| 摘 要： | 介绍了国内外目前以PSA技术进行空气分离制备氧气所用沸石分子筛吸附剂的研究状况。从研究结果来看，N2吸附容量和N2／O2分离选择性的提高主要通过对沸石分子筛4A和13X进行离子交换，以对其表面进行改性，从而调整对N2、O2的吸附性能。另外，沸石分子筛制备过程中的硅铝比和成型条件等对N2和O2的吸附也有一定的影响。

| Abstract: | This paper reviewed research of zeolite adsorbents for preparation of oxygen through the air separation by PSA technology.The result indicated the capacity of nitrogen adsorption and the selectivity of nitrogen/oxygen can be improved through using ion-exchanged 4A and 13X type zeolite by various cations.Meanwhile,the other influence factors are also discussed,such as silicon and aluminum ratio in the preparation process and the form condition. |
