Method for reducing NOx with an activated catalyst

摘要

A method of reducing NOX within a gas stream includes the step of placing a NOX reducing catalyst within a flue gas stream. The NOX reducing catalyst activity is enhanced by applying a separate activating source that significantly improves removal of NOX from the flue gas stream. The NOX reducing catalyst may be a stationary NOX reducing catalyst structure positioned in the flue gas stream. Alternately, the NOX reducing catalyst may be injected into the flue gas stream as a NOX reducing catalyst powder. The NOX reducing catalyst powder may be subsequently gathered in a particulate collection device. The NOX reducing catalyst may be further activated in the particulate collection device. The operation of separately activating the NOX reducing catalyst may be implemented by applying electromagnetic energy to the NOX reducing catalyst, by applying an electric field to the NOX reducing catalyst, by applying electric current through the NOX reducing catalyst, or by applying a magnetic field to the NOX reducing catalyst.
