Paprametric survey on no removal in an intermittent di-electric barrier discharge by one-cycle sinusoidal power source

NO gas is directly decomposed using an intermittent dielectric barrier discharge (DBD). The power source for generating the DBD is a one-cycle sinusoidal (OCS) output so as to easily control the electrical power consumed in the DBD plasma. The fundamental frequency of the OCS power source is 150 kHz. As a parametric survey for finding an efficient NO removal, the influencing factors behaves as follows: Applied voltage: high but low is desirable, Gas temperature: high, Gas flow rate: low, Repetition rate: low, NO concentration: high, Additive gas: argon diluted ammonia with a high concentration, Consumed energy: high but low is desirable, Oxygen: none. Pursuing the optimization for the NO decomposition, the energy efficiency of over 80 g/kWh is obtained in the absence of oxygen contained in NO/N2 gas.
