The adsorption/desorption characteristics of toluene vapors filled with activated carbon(AC) were studied. Adsorption performance of AC was investigated according to flow rate, moisture content, and other factors. The breakthrough time was shortened as the flow rate and moisture content increased. The AC loaded with toluene was regenerated by programmed heating and pressure. AC was regenerated well, as the conditions of heating temperature(80oC) and pressure(100 torr) were appropriate. Toluene is more easily removed at low temperature than through thermal desorption methods. The test of AC regeneration was carried out three times.
