Abstract
A NO reduction method includes treating a first gas containing NO , producing a second gas containing NO , reducing a portion of the NO in the second gas to N , and producing a third gas containing less NO than the first gas, substantially all of the third gas NO being NO. The method also includes treating the third gas, producing a fourth gas containing NO , reducing a portion of the NO in the fourth gas to N , and producing a fifth gas containing less NO than the third gas, substantially all of the fifth gas NO being NO. Treating the first and/or third gas can include treatment with a plasma. Reducing a portion of the NO 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.
