“…Non-thermal dielectric barrier discharges (DBDs) plasmas, with the addition of a dielectric barrier or multiple barriers such a quartz or other materials with high dielectric constants in the discharge gap, are the most viable nonthermal plasma sources and allow reactive species to be generated under mild conditions like room temperature and atmospheric pressure and possess high potential for cleaner, efficient synthetic chemistry [11][12][13][14][15][16][17][18]. Furthermore, plasmasolid-liquid systems are attracting more and more attention owing to their broad range of establish and promising applications [19][20][21][22].…”

An atmospheric, dielectric-barrier discharge µ-plasmatron was designed, fabricated, and applied to synthesize a methylated organometallic complex. The design comprises counter-current flow to packed-bed microstructures to facilitate gas–liquid and plasma–liquid mixing. Micropillars arranged in a staggered configuration served as a porous media for the optimum 2D mixing of components that replenish plasma-liquid interfaces. Longitudinal dispersion was characterized through residence time distribution (RTD) measurements. The experimental RTD data were then described by an axial dispersion model with a time delay parameter. Levenspiel number (lv) indicating the intensity of axial dispersion was estimated in the range of 20.1–374, indicating that a dispersion model should be accounted for in plasma-assisted reaction kinetics development. Stable plasma excitation of methane-helium gas mixtures was observed within the 2D porous media, by in-situ optical emission spectra, while applying an alternating high voltage across the dielectric barrier. This novel technique made it possible to confirm in-situ formations of methyl radicals. Interestingly, the porous media served as a static mixer as no discrete plasma streamers were observed. To investigate its utility, an example homogeneous cobalt catalyst was injected into the µ-plasmatron and methylated. Our findings potentially introduce a new plasma-assisted reactor design and methodology for the synthesis of methylated cobaloxime.

According to experts, the power-generating complex in the entire chain from fuel production to the thermal energy application efficiency of the use of energy resources is only 44 %. That necessitates the researching of ways to enhance efficiency of organic fuel burning. One of the way to solve the problem is the burning fuel in the swirl burner with using of ionizated air. Domestic and international researches have shown that atomic oxygen increases the completeness combustion and reduces the number emitted into the atmosphere of pollutant emissions. At present, the reduction of air pollution of toxic substances allocated by industrial enterprises, is one of the most important problems facing humanity. Air pollution has a unhealthy exposure for humans and the environment. In this paper estimated effectiveness of existing chemical kinetic mechanisms of natural gas burning for the swirl burner and mechanisms unhealthy emissions produced based on the results of the evaluation. The purpose of work is to increase the effectiveness of fuel combustion and technical and economic, as well as environmental indicators in the swirl burner on the heat-and-power plant.
