Activated carbon has been used as an adsorbent for various industrial applications, such as solvent recovery, gas separation, catalytic reaction or conversion, and deodorization. In this study, the effect of residual water on the adsorption characteristics of ethylene dichloride (EDC) onto a pellet-type carbon adsorbent was investigated. Isothermal adsorption column was used to study the effects that the feed concentration, flow rate, and residual water in the activated carbon pellet have on the adsorption characteristics of EDC. Desorption characteristics of residual water in the activated carbon were also studied. The water content in the activated carbon was controlled in the range from 0 to 20% (w/w). The experimental data for the adsorption equilibrium of EDC on the activated carbon is expressed well by the Sips isotherm. The adsorption capacity of EDC decreased upon increasing the temperature and residual water content. The theoretical breakthrough curves plotted using a linear driving force (LDF) model represent the experimental data very well.
