Abstract:

The influences of frequency on nitrogen fixation of dielectric barrier discharge in air were studied by electrical diagnostics, gas detection and infrared detection methods. The system power, nitrogen oxide concentration, voltage–current waveform, dielectric surface temperature distribution and filamentous discharge pictures were measured, and then the energy yield was calculated; paper studied their changing tendencies in the presence of frequency. Results show that frequency has strong influences on nitrogen fixation. When the parameters of reaction chamber and amplitude of applied voltage is fixed, with the increasing of frequency, the system power increases; in 5–10 kHz, nitrogen oxide gas concentration up to 1113.7 mg m-3, and 7 kHz is the optimal nitrogen fixation frequency whose energy yield is 20.5 mg (m3 W)-1.

Key words: nitrogen fixation, dielectric barrier discharge, frequency, energy yield
