摘要
A vapor phase adsorption system employing an adsorbent for removing a volatile organic compound from an air stream to produce a purified air effluent in which the adsorbent first adsorbs the compound and is then regenerated by raising the temperature of the adsorbent to a maximum desorption temperature, which employs an improvement which comprises an unloading compound pre-adsorbed on the adsorbent, wherein the unloading compound is an organic compound having a boiling point greater than that of the volatile organic compound and having an equilibrium loading capacity on the adsorbent at the maximum desorption temperature greater than the equilibrium loading capacity of the volatile organic compound.
