“…Rates of the ozone formation reactions increase with specific input energy, which leads to an increase of ozone concentration. Simultaneously, part of the energy injected into the reactor could be converted into heat to raise the temperature in the plasma zone, favoring the following reactions which cause a decrease of ozone concentration: According to the experimental results, it can be concluded that the negative effect of heating is not playing the major role for ozone formation in the range of energy density investigated in the present study.…”

A coaxial nonthermal plasma (NTP) reactor was used for the removal of nitric oxide in mist. The effects of discharge gap, thorn number, tooth slice number as well as discharge polarity on NO oxidation and NO x removal were investigated. Decreasing the discharge gap is favorable for the NO oxidation and NO x removal. The mist is almost captured completely even under a relative low input energy. Increasing the thorn number of discharge slice or tooth slice number facilitates the energy input in the plasma reactor and thus enhances the NO oxidation and NO x removal under a fixed applied voltage. The energy efficiency for the positive DC (4.5 g NO/kWh) is three times as much as that for the negative DC (1.5 g NO/kWh), corresponding to NO oxidation efficiency of around 80%.

“…In multichannel DBD, when the energy yield of ozone is 80 g/kWh [26], the ozone concentration is 15 g/m 3 , only 8.3% of this work. For the surface DBD, when the energy yield of ozone is 75 g/kWh, the ozone concentration is 21.1% of this work [27]. In packedbed plasma [28], when the energy yield of ozone is 108 g/kWh, the ozone concentration is 2.65 g/m 3 .…”

Discharge mode is an important parameter for ozone synthesis by dielectric barrier discharge (DBD). Currently, it is still challenging to stably generate glow discharge with oxygen at atmospheric pressure. In this paper, a DBD reactor with a layer of silver placed between the electrode and the dielectric layer (SL-DBD) was developed. Experimental results show that both streamer and glow corona discharge were stably generated under sinusoidal excitation with a 0.5 mm discharge gap in a parallel-plate DBD, due to the increased electric field strength in the discharge gap by the silver layer. It was also found that, in the SL-DBD reactor, glow corona discharge enhances the discharge strength by 50 times. The spectral peak of O at 777 nm in SL-DBD is increased to 28,800, compared with 18,389 in a reactor with a streamer only. The SL-DBD reactor produces ozone with a concentration of as high as 150 g/m3 and shows good stability in an 8 h durability test.

“…On the other hand, the insulating barrier in a SDBD is sandwiched between the two electrodes and the discharge develops along the surface of the dielectric plate. SDBD is widely investigated in different applications, such as airflow control [6], volatile organic compounds (VOCs) removal [7], ozone production [8,9], and bactericidal agents [10]. The ozone, being a powerful oxidant [11], has many applications in industry.…”

The aim of this work is to develop an efficient plasma reactor for ozone production. The electrical characterization of the developed reactor, including the current-voltage waveform and the consumed power, is investigated at different reactor configurations (including ground-electrode width, number of electrodes, and volume of the reactor) and operating parameters (including the air flow rates and energy density). The performance of the developed reactor for ozone production is evaluated. It is observed that the consumed power increased linearly with increasing the ground-electrode width and the number of electrodes, while the reactor volume and the flow rates have no noticeable effect on the consumed power. It is also found that the increase of the plasma area by increasing the width of the ground electrode is preferable than its increase by increasing the number of electrodes. This is attributed to the decrease of the power loss in the dielectric material. In addition, an optimum size of the reactor is obtained, as the higher and the smaller ratio of the reactor volume to the plasma area are not efficient.
