Abstract
A system and method for the reduction of NOx and CO contaminants using an ion-exchange resin media having lower-valency ions of the transitional metal elements, such as ferrous ions, cuprous ions and/or manganese ions, such that gases containing NOx and/or CO contaminants may be passed over the media so that the contaminants are absorbed by the lower-valency ions of the transitional metal elements, the media configured so that it can be regenerated to remove the NOx and/or CO contaminants. Regeneration includes exposing the media to a heated stream of hydrogen gas or exposing the media to hydrogen ions in an electrochemical cell.
