“… 91 It was observed that using gliding arc plasma could provide up to 35% improvement in conversion and energy efficiency when compared to pulsed plasma with parallel electrodes, most likely due to the distribution of the discharge over a larger gas volume. 92 …”

“…Bidgoli et al applied a pulsed reactor with an electric arc moving much faster than the gas flow to direct pyrolysis of CH 4 . Gliding sparks produced by self-stimulated acoustic waves allow for chemical conversion rate as high as 50%, having much better performance in comparison with the conventional pulsed plasmas [22]. Several authors have also successfully used GA reactors to stimulate the growth of seeds of plants, such as wheat, Thuringian Mallow or hemp [23][24][25].…”

The gliding arc discharge plasma reactors are known as a source of non-equilibrium plasma at atmospheric pressure. In the present study, generation of dominant reactive oxygen and nitrogen species in gaseous and liquid phase in water by the compact gliding arc device (mini-GAD) and corresponding bactericidal effects were investigated. Water and phosphate buffer solutions were used as model liquids. Mini-GAD is a strong source of nitrogen oxides (up to 800 ppm NO and 200 ppm NO 2) that result in high concentrations of nitrites and nitrates in water solutions. The highest bactericidal efficacy towards Escherichia coli was achieved for non-buffered water solution.

“…The non-thermal plasma has the nature of non-equilibrium in the electron and the heavy particle temperature [15], which is beneficial for the initiation of chemical reaction under relatively lower temperature and energy input [4,16]. However, the chemical process usually suffers from lower conversion efficiency and lower throughput in non-thermal plasma reactor.…”

Thermal plasma pyrolysis is a powerful technology for converting waste or low-value materials to valuable gaseous hydrocarbons. This paper presents for the first time the hydropyrolysis of n-hexane and toluene in a rotating-arc plasma reactor. Effects of the mole ratio of H/C in the feed, power input and magnetic induction were investigated to evaluate the reaction performance. A lower H/C ratio could lead to a lower yield of C 2 H 2 and lower specific energy consumption, and there existed an optimum range of power input for both n-hexane and toluene pyrolysis within the investigated range. The yield of C 2 H 2 in n-hexane and toluene pyrolysis could reach 85% and 68%, respectively, with respective specific energy consumption (SEC) of 13.8 kWh/kg·C 2 H 2 and 19.9 kWh/kg·C 2 H 2 . Compared with the results reported in literature, the rotating-arc plasma process showed higher C 2 H 2 yield and lower energy consumption, which is attributed to the better initial mixing of the reactant with the hot plasma gas and the more uniform temperature distribution.
