摘　　要：利用多孔材料在低温低压下能够吸附大量气体这一特点所进行的低温吸附抽气，是获得清洁无油真空的有效手段，吸附等温线是设计低温吸附抽气产品不可缺少的依据。本文建立了测定多孔物质在低温低压下吸附性能的实验装置，并在此装置上测定了ＧＨ－０、ＧＨ－１、ＧＨ－１６Ａ、Ｌ－Ｔ四种型号的国产优质活性炭的吸附等温线的性能数据，为低温吸附抽气产品提供了依据。北京光华木材厂生产的ＧＨ－０型椰壳活性炭平衡吸附量大，且吸附速率快，平衡压强低，是最佳的选择。In this paper an experimental equipment had been set up to determine adsorption isotherms and other equilibrium data for the adsorption of air on heterogenous material like molecular sieve 5 and activated carbon.Four types of activated carbons named GH - 1,GH -0,LT,GH - 16A had been measured in this paper.GH - 0 coconut activated carbon has the best adsorption characteristic among the four.It is the best selection.
