| Abstract: | Partial selective catalytic reduction of NO by hydrogen has been studied on non uniform activity distribution Pd/Al 2O 3 catalyst with low Pd content in the excess of oxygen. Experimental results show that conversion of NO can be reached 80%～100% at low temperature.NO is inhibiting to hydrogen oxygen reaction at approximately 20℃.NO reduction reaction begins after starting of hydrogen oxygen reaction and they are parallel reactions. |
