摘要:

测定了丙酮-正己烷、甲苯-正己烷、苯-正己烷、正戊烷-正己烷四个二组分气体在部分石墨化的灯黑上的吸附等温线,并测定了单组分气体吸附等温线.对比了上述四个二组分气体,分别在硅胶、硅烷化硅胶和灯黑上吸附的十二个吸附体系的吸附规律.结果表明,二组分气体在吸附剂上的竞争吸附的强弱,基本上可以通过它们的纯组分气体在吸附剂上第一层吸附热Q1数值的大小加以预测.

Abstract:

In this paper, the binary adsorption isotherms of acetone-n-hexane, toluene-n-hexane, benzene-n-hexane and n-pentane-n-hexane on partial graphitizing lamp black are presented. The adsorption isotherms for pure gas are also obtained. The adsorption regularity of these four binary gas adsorption on silica gel, silylanization silica gel and partial graphitizing lamp black is summerized respectively. It will be seen from the experimental results that the adsorption behavior of the vapor mixtures can be predicted basicoly from the isotherms ofo pure components. The extent of predominant adsorption can be predicted by the first layer adsorption heat of the individual pure components.

Key words: Binary gas adsorption on lamp black, Acetone-n-hexane, Toluene-n-hexane, Benzene-n-hexane, n-pentane-n-hexane, Binary gas solid adsorption isotherm
