“…Up till now, several types of plasma reactors have been investigated for CO2 conversion, including corona discharges, glow discharges, microwave discharges, radio frequency discharges, gliding arc discharges and dielectric barrier discharges [16][17][18][19][20][21][22][23][24][25][26]. In this work, a dielectric barrier discharge (DBD) reactor is used, since it operates at ambient temperature and atmospheric pressure, can easily accommodate packing materials and be scaled up to industrial conditions.…”

Plasma catalysis is gaining increasing interest for CO2 conversion, but the interaction between the plasma and catalyst is still poorly understood. This is caused by limited systematic materials research, since most works combine a plasma with commercial supported catalysts and packings. In the present paper, we study the influence of specific material and reactor properties, as well as reactor/bead configuration, on the conversion and energy efficiency of CO2 dissociation in a packed bed dielectric barrier discharge (DBD) reactor. Of the various packing materials investigated, BaTiO3 yields the highest conversion and energy efficiency, i.e., 25% and 4.5%.Our results show that, when evaluating the influence of catalysts, the impact of the packing (support) material itself cannot be neglected, since it can largely affect the conversion and energy efficiency. This shows the large potential for further improvement of packed bed plasma reactors for CO2 conversion and other chemical conversion reactions by adjusting both packing (support) properties and catalytically active sites. Moreover, we clearly prove that comparison of results obtained in different reactor setups should be done with care, since there is a large effect of the reactor setup and reactor/bead configuration.

The continually increasing use of fossil fuels throughout the world has caused carbon dioxide (CO2) concentration to grow rapidly in the atmosphere. Increasing CO2 emissions are the major cause of global warming, and a number of studies have been done to show the predicted effects of global warming. This paper reported a method of degradation of CO2 through dielectric barrier discharge (DBD) plasma; a microplasma reactor was used to decompose CO2 into carbon monoxide (CO) at normal atmosphere and room temperature. Gas chromatography was used to analyze the compositions of the outlet gases. No carbon deposits were found in this work. A variety of parameters, such as feed flow rate, input power, frequency, discharge gap, and external electrode length were investigated. The effects of these parameters on CO2 conversion were examined. At the same time, the effects of feed flow rate and input power on the energy efficiency were studied. The results indicated that a higher conversion of CO2 can be realized with a lower feed flow rate, a limited higher input power and a lower frequency. However, a higher feed flow rate and a lower input power were beneficial for energy utilization. The discharge gap had a little effect on the conversion of CO2 in microplasma reactor. In this work, the highest conversion of CO2 was 18.0%, and the highest energy efficiency was 3.8%. The DBD microplasma is a promising method for decomposing CO2.© 2014 Society of Chemical Industry and John Wiley & Sons, Ltd

“…4,5 The air inside the switchgear is composed of 28% oxygen, 71% nitrogen, and a minimal amount of CO 2 . The proportion of each component remains unchanged and stable under normal circumstances; the oxygen in the air generates ozone (O 3 ) during PD; nitrogen (N 2 ) undergoes numerous reactions to produce different types of nitrogen oxide (NO x ), 6 such as NO, NO 2 , and NO 3 ; PD causes the decomposition of the solid-insulating medium to produce certain types of carbon oxide (CO x ) 7,8 such as CO and CO 2 . The long-term existence and continuous development of PD increase the content of decomposing components in the air.…”

Air-insulated switchgear cabinets play a role in the protection and control of the modern power grid, and partial discharge (PD) switchgear is a long-term process in the non-normal operation of one of the situations; thus, condition monitoring of the switchgear is important. The air-insulated switchgear during PD enables the decomposition of air components, namely, O and NO. A set of experimental platforms was designed on the basis of the principle of ultraviolet differential optical absorption spectroscopy (UV-DOAS) to detect O and NO concentrations in air-insulated switchgear. Differential absorption algorithm and wavelet transform were used to extract effective absorption spectra; a linear relationship between O and NO concentrations and absorption spectrum data were established. O detection linearity was up to 0.9992 and the detection limit was at 3.76 ppm. NO detection linearity was up to 0.9990 and the detection limit was at 0.64 ppm. Results indicate that detection platform is suitable for detecting trace O and NO gases produced by PD of the air-insulated switchgear.
