Abstract—Experiments were carried out to study adsorption of toluene a volatile organic compound (VOC) on the granular activated carbon. The range of experimental variables studied is as follows: inlet gas concentration (7000 – 11500 ppm), gas flow rate (50 – 70 ml/min) and height of the adsorbent bed (0.015 – 0.025 m). The breakthrough curves were then drawn between ratios of outlet gas concentration to inlet gas concentration versus time for different operating conditions. A mathematical model was developed to predict the VOC breakthrough characteristics on granular activated carbon. The model incorporated the effects of the gas-particle film mass transfer resistance, adsorbent pore diffusion and instantaneous local adsorption equilibrium at the pore surface. The experimental data and the corresponding model simulated results were compared and found to be in good agreement.
