“…This raises the fluid phase composition of the less selectively adsorbed component to such an extent that it rises to a peak composition above that of the inlet composition. The roll-up or overshoot phenomenon had also been demonstrated by Dexin and Youfan (1988) for the adsorption of methane, ethane, and carbon dioxide mixture on 4A molecular sieve zeolite. Since ethane was more selectively adsorbed than carbon dioxide, and methane was less selectively adsorbed than carbon dioxide, carbon dioxide displaced methane, and ethane displaced carbon dioxide.…”

Breakthrough curves for the adsorption of propane, n-butane, and iso-butane mixture on 5A molecular sieve zeolite were obtained experimentally and theoretically at a constant temperature of 301 K. The equilibrium model and linear driving force model were used to predict the experimental breakthrough curves for this multicomponent mixture. The equilibrium model gave a satisfactory fit for experimental data. The model equations were solved by a numerical method based on backward finite difference with a fixed griding technique. The effects of feed flow rate (0.552-3.496 l/ min), feed concentration (60.72-141.68 mmol/l), and adsorbates composition (58.75-75.32%) on these breakthrough curves were examined.

The equilibrium model gave a satisfactory fit for experimental data. The model equations were solved by a numerical method based on backward finite difference with a fixed griding technique. The effect of feed flow rate (0.385-3.465 l/ min), feed concentration (60.72-182.16 mmole/l), and adsorbates composition (11.73-20.11%) on the breakthrough curves were examined.
