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
