摘要: 测定了丙酮-正己烷、甲苯-正己烷、苯-正己烷、正戊烷-正己烷4个二组分以及各单组分气体在硅胶上的吸附等温线.实验结果表明二组分气体在硅胶上的竞争吸附的强弱,可以通过比较它们的纯组分气体在硅胶上第一层吸附热Q1数值的大小加以预测.

关键词: 二组分气-固吸附, 丙酮-正己烷、甲苯-正己烷、苯-正己烷、正戊烷-正己烷, 吸附等温线

Abstract: In this paper,the binary adsorption isotherms of acetone-n-hexane,toluene-n-hexane,benzene-n-hexane and n-pentane-n-hexane on silica gel are presented.The adsorption isotherms for pure gases are also obtained.It will be seen from the experimental results that the adsorption behavior of the vapor mixtures can be predicted from the isotherms of pure components.The extent of predominant adsorption can be predicted from the first layer adsorption heat of the individual pure component.

Key words: Binary gas-solid adsorption, Acetone-n-hexane, Toluene-n-hexane, Benzene-n-hexane, n-Pentane-n-hexane, Adsorption isotherm
