ABSTRACT
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 x 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 degrees C. Gas velocity of empty bed affected the peak value of concentration of the toluene, and practical value was 0.2-0.4 m x s(-1).
