Abstract
PURPOSE: To increase NOx removal ratio and to decrease the quantity of unreacted NH3 sharply so as to prevent secondary environmental pollution by making the flow of NOcontaining gas contact with NH3, and then with O2-containing hydrocarbon in two stages, both in the presence of sufficient O2.
