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.
Claims4
A method of reducing NOx and CO contaminants, the method comprising:
- providing an ion-exchange resin media comprising lower-valency ions of the transitional metal elements,
- directing gases containing NOx and/or CO contaminants over the media such that the contaminants are absorbed by the lower-valency ions of the transitional metal elements, and
- regenerating the media to remove the NOx and/or CO contaminants, wherein regenerating comprises exposing the media to a heated stream of hydrogen gases.
