[Adsorption-desorption performance of honeycomb-shaped activated carbon].

Honeycomb-shaped activated carbon is useful to control organic gas pollution of large air-flow and low concentration.Effects of adsorbents,toluene concentration,velocity of empty bed and temperature of desorption on its adsorption-desorption performance were studied by conducting on dynamic experiments.Results shown that adsorption properties of honeycomb-shaped activated carbon were increased with decreasing of the inlet toluene concentration under the condition of certain outlet toluene concentration,and gas velocity of empty bed was recommend as 1.2-1.8 m·s-1.With increasing of the desorption temperature,the outlet toluene concentration appeared peak-value and fluctuated widely,and the recommended desorption temperature was 90℃.Gas velocity of empty bed affected the peak value of concentration of the toluene,and practical value was 0.2-0.4 m·s-1.
