| Abstract: | Simple component equilibrium data for ethylene ,ethane and carbon dioxide on AE have been determined at 298. 2 K and pressures from 13. 3 to 101. 3 kPa. The adsorption data have been analyzed in terms of the vacancy solution model isotherm. The model provides an excellent correlation of pure component isotherms over the entire pressure range. It is shown that equilibrium data for the adsorption of single gases were correctly predicted by the four model parameters (limiting molecular Volume ,Henry's constants Li1 and two Wilson's parameters (A13 ,A31) derived from analysis of the pure component isotherm. The experimental results were given the reasonable explaination in terms of the adsorbent physichemical properties. |
