Abstract

PURPOSE: To reactivate deteriorated activated carbon catalyst and to restore the NO2-removal ratio by washing the deteriorated activated carbon catalyst with water to remove selectively ammonium sulfate formed on the catalyst. To the activated carbon catalyst is adhered halogen for removing SOx, NOx.
