<p>A NOx reduction method includes treating a first gas containing NOx, producing a second gas containing NO2, reducing a portion of the NO2 in the second gas to N2, and producing a third gas containing less NOX than the first gas, substantially all of the third gas NOx being NO. The method also includes treating the third gas, producing a fourth gas containing NO2, reducing a portion of the NO2 in the fourth gas to N2, and producing a fifth gas containing less NOX than the third gas, substantially all of the fifth gas NOx than the third gas, substantially all of the fifth gas NOx being NO. Treating the first and/or third gas can include treatment with a plasma. Reducing a portion of the NO2 in the second and/or fourth gas can include reducing with a catalyst. The method can further include controlling energy consumption of the plasmas independent of each other.</p> |
