| The adsorption of methyl methacrylate (MMA) on a coconut shell activated carbon (CSAC) was studied,�� and the effects of concentration,�� flow velocity�� adsorption temperature and water vapor precondition which acted on the performance of VOCs adsorption were discussed. The results illustrated that the CSAC had a good capability of adsorbing MMA. With changing of MMA inlet concentration and quantity,�� the time of adsorption equilibrium would move forward or backward. Temperature swing adsorption experiment proved that reducing temperature would promote the adsorption performance of the CSAC. When the humidity was 50%,�� the adsorption behavior of the CSAC was not influenced obviousely�� which indicated that the activated carbon had a good hydrophobicity. Coconut shell activated carbon was regenerated for many times,�� it still could remain its good capacity of adsorption. |
