The dynamic adsorption behaviors of benzene vapor on phosphoric acid‐activated carbon fiber (ACF‐P) were investigated by gas chromatography. The experimental results showed that ACF‐P that was activated at >350 ° C, like steam‐activated carbon fiber (ACF‐W), has good dynamic adsorption properties for benzene vapor. However, the saturation adsorption capacities of ACF‐P and ACF‐W are different. The dynamic adsorption conditions apparently do not affect the effluent concentration before the breakthrough point, but do change the operation loading and usage efficiency. The adsorbed ACF‐P can be regenerated, and good dynamic adsorbability can be recovered by heating treatment. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 83: 1841–1847, 2002
