Climate change has become the most serious problem which we are environmentally confronting these days. NOx and N2O are components causing global warming effect more than CO2 and are greatly emitted from fuel combustion systems.Though there are known some technologies like NH3 SCR,it is still not easy to remove NOx and N2O efficiently when O2 is present.In this presentation, we are introducing an MMO catalyst AFC111 which has shown remarkable performance in the removal of NOx and N2O when used as a trap for NOx and N2O in the presence of O2.NO and N2O are adsorbed first displaying higher selectivity compared with O2, and then they are desorbed by CO.The catalyst was operated cyclically with transient mode. As a result of this cyclic operation, it may be concluded that the catalyst has been proved as an excellent LNT material and the reduction efficiency was getting higher and higher by cutting cycle time.
