摘　　要：建立了在低温低压下测定多孔物质吸附性能的试验装置。在此装置上测定了ＺＸ－１５，ＫＺ１５－２，ＤＸ－３０，ＰＪ－２０，ＺＫ－４０，ＤＸ－４０，ＧＨ－０与５Ａ分子筛１∶１混合吸附剂等７种国产优质活性碳（分子筛）吸附空气的吸附等温线。这些数据为低温吸附抽气产品设计提供了可靠依据。文中的试验条件下生产的ＺＸ－１５活性碳在吸附空气时，吸附量大、平衡压强低、吸附速率较快且价格低廉，是最佳选择。An experimental equipment is set up to measure the adsorption characteristics of porous material at low temperature and low pressure. The adsorption isotherm of six kinds of activated carbon such as ZX-15,KZ15-2,DX-30,PJ-20,ZK-40,DX-40 for air and adsorption isotherm of mixed adsorbent of sieve 5A and GH-0 coconut activated charcoal with mass ratio 1∶1 for air are measured on the equipment.The experiment tests show that ZX-15 has the best adsorption characteristics among the porous materials which are measured. Moreover, the data of adsorption isotherm are of high value to design the cryogenic adsorption equipment.
