Adsorption of benzene and toluene vapors on activated carbon fiber at 298, 323, and 348 K

Abstract

The adsorption equilibria for benzene and toluene vapors on commercially available activated carbon fiber were measured by a static volumetric technique. The equilibrium measurements were made at 298.15, 323.15, and 348.15 K and pressures up to 8.7 kPa for benzene and 3.4 kPa for toluene, respectively. The results were correlated by the Dubinin-Astakhov equation, which is a fundamental theoretical relation for describing the filling of micropores.
