英文摘要	采用水溶液离子交换法制备了高Li+交换度的4A、13X和LSX分子筛,并在25℃下测定了它们的静态吸附等温线和动态穿透曲线.研究发现,高Li+离子交换度的4A、13X和LSX分子筛都具有较大的氮吸附容量和较高的氮氩分离选择性,说明高Li+离子交换度的4A、13X和LSX分子筛是较好的氮氩分离吸附剂.从动态穿透曲线结果来看,所研究的三种分子筛都有一个最优的吸附分离压力,在本文研究的压力范围内,这个最优压力在0.6 MPa附近.对比高锂交换度的三种分子筛,以高锂交换度的LSX分子筛的氮氩吸附分离性能最好.; The 4A, 13X and LSX zeolites were ion exchanged with Li+ repeatedly in water solution, then the adsorption isotherms and breakthrough curves of these zeolites were measured at 25 degreesC. The data demonstrate that 4A, 13X and LSX highly ion-exchanged with Li+ have higher adsorption capacity and better adsorption selectivity for N-2 over Ar. It is clear that the highly Li+ exchanged zeolites are good adsorbents for separation of N-2 and Ar. From breakthrough curves we know that the zeolites near completely exchanged with Li+ have a suitable pressure for the adsorption separation of N-2 and Ar. In the pressure range we studied, the best pressure is about 0.6 MPa. Comparing with the data from the breakthrough curves of the three highly Li+ exchanged zeolites we conclude that highly Li+ exchanged LSX has better properties for the separation of N-2 and Ar than the other two zeolites.; 国家重点基础研究发展计划(973计划); http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000222794400004&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 1; 7; 684-689; 20
