Adsorption equilibria of toluene and gasoline vapors on activated carbon

The adsorption equilibria of toluene and gasoline vapors on activated carbon were measured by a static volumetric method. The equilibrium experiments were conducted at (298.15, 318.15, 338.15, 358.15, and 378.15) K and pressures up to 3.1 kPa for toluene and 8.0 kPa for gasoline. The experimental data obtained were correlated by the UNILAN and Sips models, which are generally used for microporous adsorbents such as activated carbon. The Henry constant was calculated to characterize interactions between adsorptive and adsorbent.
