PURPOSE:To provide a catalyst capable of efficient removal of NOx from waste combustion gas contg. NOx, CO and more oxygen than that reacting theoretically with unburned matter such as hydrocarbon, e.g. waste combustion gas from a fixed burner or a gasoline engine, a diesel engine, etc., performing combustion under the condition of excess oxygen and to provide a method for removing NOx with the catalyst. CONSTITUTION:Silver or silver oxide and at least one kind of metal selected among Sn, Al, Ga and In and/or oxide of the metal are carried on a porous inorg. oxide to obtain the objective catalyst for removal of NOx. |
