Abstract
In this study, we have investigated the characteristics of adsorption and desorption of toluene, methyl ethyl ketone (MEK) and their binary component using activated carbon. The BET analysis was performed to identify the characteristics of the activated carbon, and the desorption characteristics with temperature were examined to find out an optimum desorption temperature. Ten cyclic experiments of adsorption-desorption were performed, where each adsorption temperature was maintained at room temperature and desorption temperature at upto $120^{\circ}C$. In case of single component cyclic test, the efficiencies of adsorption and desorption decreased as the cycle increased. MEK which has lower affinity with activated carbon than toluene showed lower efficiencies of adsorption and desorption. In case of binary component cyclic test, a typical roll-up phenomenon was observed during adsorption process, where MEK reaches at breakpoint first and then was swept out by toluene.
