摘要： A method of removing at least nitrogen oxides from an exhaust gas comprises producing reducing agents including at least hydrogen gas upstream of a conversion catalyst; diverting a portion of the exhaust gas to a location upstream of the conversion catalyst; reacting the reducing agents with nitrogen oxides present in the portion of the exhaust gas to produce a nitrogen-containing compound reducing agent using the conversion catalyst; introducing the nitrogen-containing compound reducing agent upstream of a SCR catalyst; mixing the nitrogen-containing compound reducing agent with a second portion of the exhaust gas upstream of the SCR catalyst; and reacting the nitrogen-containing compound reducing agent with nitrogen oxides present in the second portion of the exhaust gas at the SCR catalyst.
