摘要： Systems and methods of removing at least nitrogen oxides from an exhaust fluid generally include dividing a flow of an exhaust fluid comprising a concentration of nitric oxide into three types of flow-through cells. The first flow-through cell comprises a catalyst configured to reduce the nitric oxide with a reductant to form a first feedstream comprising nitrogen containing species derived therefrom. The second flow-through cell comprises a catalyst configured to oxidize nitric oxide to form a second feedstream comprising nitrogen dioxide. The third flow-through cell does not change the nitric oxide concentration and form a third feedstream comprising nitric oxide. After flowing through the three different types of cells, the feedstreams are mixed to form a homogenous mixture and then fed to a catalyst bed configured to convert the nitrogen containing species, the nitric oxide, and the nitrogen dioxide to a fluid comprising nitrogen gas and water.

摘要： Systems and methods of removing at least nitrogen oxides from an exhaust fluid generally include introducing a first reducing agent and a hydrogen gas co-reductant agent into the exhaust fluid upstream of a catalyst bed optimized for a hydrocarbon selective catalytic reduction process to reduce nitrogen oxides present in the exhaust fluid and then reacting residual nitrogen oxides in a second catalytic bed optimized for an ammonia selective catalytic reduction process. The use of hydrogen gas permits efficient reduction of nitrogen oxides over a wide temperature range, which is minimally affected by the presence of sulfur dioxide in the exhaust fluid.
