We have investigated the applicability of supercritical carbon dioxide (ScCO_2) extraction to cleaning technology of air filters, particularly chemical filters. In this study, the regeneration of chemical filters loaded with gaseous toluene was studied by measuring the breakthrough curve and the weight recovery via ScCO_2 extraction. The experiments have been carried out at various P conditions. The results revealed that the regenerative ratio of filter for the treatment at 6MPa and 40℃ was 47%, whereas that at pressures of 8, 10, 15, 20MPa, and 40℃ was above 90%. These results indicated that filter media will be cleaned efficiently if the CO_2 is in the supercritical state compared with the liquid CO_2, because of its high diffusivity.
