Adsorption Isotherms of Toluene and Gasoline Vapors on DAY Zeolite

Abstract

The adsorption equilibria of toluene and gasoline vapors on DAY zeolite 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 2.5 kPa for toluene and 7.8 kPa for gasoline. The experimental data obtained were correlated by the Toth and UNILAN models, which are generally used for microporous adsorbents such as zeolite.
