The removal efficiency against hydrogen chloride (HCI) of KOH-added activated carbon, which was developed to improve removal efficiency aeainst acid gases in atmosphere, was examined by comparison with that of an untreated activated carbon. The removal efficiency of KOH-added activated carbon aeainst HCl was superior to that of an untreated activated carbon. Furthermore, a prediction method for breakthrough curves by numerical simulations was studied. The simulated breakthrough curve agreed well with the experimental result of KOH-added activated carbon. And breakthrough curves were predicted on a condition of atmospherical concentration.
