NOx 제거용 저온 플라즈마 반응기에서의 플라즈마 화학 및 입자 성장

The plasma chemistry and particle growth in the low temperature plasma reactor for removal of NOx

We analyzed theoretically the removal efficiency and the particle growth inside the pulse corona discharge reactor to remove NOx and investigated the effects of process variables such as the NO and NH₃ input concentrations. Most of NO is converted into NO₂ and HNO₃ and the HNO₃ reacts with NH₃ to form the NH₄NO₃ particles. About 6.4% of NO is converted into HNO₂ which form the NH₄NO₂ particles by reaction with NH₃. some of NO₂ follows the reaction pathway to form NO₃ and N₂O₅. The amount of particles formed inside the reactor is basically determined by the input NH₃ concentration. The ratio of NO to NH₃ affects the reactor length for particle formation significantly. The higher the input concentrations of NO and NH₃ are, the faster the particles grow.
