Abstract :
Nonthermal plasma technologies have been investigated for the control of NOx flue gas emissions. Previous results have shown that nonthermal plasma is able to reduce NO but cannot convert NO 2 effectively. In addition, part of the NO2 is reduced by N to form N2O. Several hydrocarbon additives, catalysts and water film combined with the nonthermal plasma process, have been investigated to enhance NOx reduction, but NOx reduction has been limited to the 70% range. As an alternative technology, the plasma-assisted chemical reactor was investigated plasma to convert NO to NO2 and the chemical reduction process to convert NO2 to N2. Three types of plasma reactors were investigated and nearly 100% NOx decomposition was achieved with minimum N2O formation
