Abstract
Adsorption/desorption characteristics of low concentration methylethylketone(MEK) and toluene vapors in beds packed with activated carbon fibers(ACF) was investigated. Performance of ACF adsorption was characterized by the equilibrium capacity, time to reach equilibrium and desorption efficiency. Experiments were carried out to define the effect of operation variables, such as feed concentration, flow rate, moisture content and bed height. The breakthrough time was shorten with the increase of temperature, flow rate and feed concentration. In addition, an increase of packed height of adsorbents lengthen the breakthrough time. The ACF loaded with MEK and toluene was satisfactorily regenerated by programed heating. It is observed that MEK is more easily removed than toluene at below temperature of $150^{\circ}C$.
