Abatement of NOx with Propene Activated by Corona Plasmas

This paper presents an improved wire-to-plate type plasma reactor for remediation of flue gas containing NO_x/SO₂, in which a nozzle electrode for injection of de-NO_x additive was installed in the front of wire electrodes to enhance the production of de-NO_x radicals. The experimental results indicate that additive activated by corona plasmas could effectively increase NO_x removal in a wire-plate type reactor; positive corona plasmas performed better when taking both the removal rates and the energy cost into consideration, under appropriate condition de-NO_x rate increased over 10% when C₃H₆ was activated by positive corona plasmas.
