| Abstract: | Experimental Henry's Law equilibrium data for linear paraffins show a well defined linear variation of adsorption energy with carbon number and a linear relationship between the entropy and energy of adsorption (compensation effect). Such correlations, are presented for sorption of linear paraffins on NaX, NaY, USY, silicalite and silica gel as well as for two commercial (faujasite based) catalysts and provide a concise way to predict the adsorptive behavior of the higher paraffins. |
