Fundamental Limits on NOx Reduction by Plasma

Abstract

<div class="htmlview paragraph">This paper discusses the gas-phase reaction mechanisms for removal of NO<sub>x</sub> in a plasma. The effect of oxygen content on the competition between the reduction and oxidation processes is discussed. The effect of the electron kinetic energy distribution on the radical production and subsequent chemistry is then discussed in order to predict the best performance that can be achieved for NO<sub>x</sub> reduction using the plasma alone. The fundamental limit on the minimum electrical energy consumption that will be required to implement NO<sub>x</sub> reduction in any type of plasma reactor is established.</div>
