摘　　要：测定了国产5A沸石分子筛、椰壳活性炭、炭分子筛对空气在液氮温度及低压下的吸附等温线及90K下椰壳活性炭的吸附等温线。提出了新型混合吸附剂(5A沸石分子筛与椰壳活性炭以1:1的混合比相混合的混合吸附剂),并测定了该混合吸附剂在液氮温度及低压下对空气的吸附等温线。本文还对这些吸附等温线进行了分析,拟合出在一定范围内适用的吸附等温式。实验结果及相应分析,可供设计吸附设备时参考使用。The adsorption isotherms for domestic molecular sieves 5A, cocos charcoal and coal sieves at liquid nitrogen temperature and low pressure, as well as for domestic cocos charcoal at 90K and low pressure are measured. A new kind of mixed adsorbent (mixing molecular sieves 5A with cocs charcoal) is raised and its isotherm for adsorbing air at liquid nitrogen temperature and low pressure is also measured. All these isotherms are analyzed, from which the adsorption isothermal equations of a cerain application range are simulated. The test results and related analysis may be adopted in the design of adsorption e- quipment.
