Abstract

Permeability of benzene or n-hexane through an activated carbon has never been seriously studied in the literature. The observation of trend of permeability curve at a certain reduced pressure for a given temperature is essential in determining flow type of an adsorbate in the porous medium. In this report, it is observed that at low pressure, surface flows dominate the transport of the adsorbate at micropores while at high pressure, gaseous viscous flow acts as a controlling mechanism at macropores. It is also believed that capillary condensation shows a significant role in transport of molecules in porous media. where when all pores are filled with condensate at pressure close to the vapor pressure. This results in a great decrease in permeability In general, for a given reduced pressure, permeability increases with temperature because of the increase in vapor pressure with temperature. A hysteresis of adsorption-desorption permeability curves for activated carbon that shown in the experiment result seems to agree with any experimental result reported in the literature for other systems.
