AC diaphragm discharge plasma
methylene blue
mechanism of destruction
post-effect
The action of AC diaphragm discharge plasma on the kinetics of methylene blue destruction in acid and alkali media is presented. It was found that the dye destruction passes through formation of the interim product stage (N,N-dimethylaniline) under both conditions. The chemical analysis of the presence of oxidizers in the solution after plasma treatment allows one to explain the post-effect.

The results of long-term research of plasmachemical technologies of pyrolysis, hydrogenation, thermochemical treatment for combustion, gasification, radiation-plasma, and complex conversion of solid fuels, including uranium-containing slate coal, and cracking of hydrocarbon gases, are presented. The use of these technologies for obtaining target products (hydrogen, hydrocarbon black, hydrocarbon gases, synthesis gas, and valuable components of the coal mineral mass) meet the modern experimental and economic requirements to the power sector, metallurgy and chemical industry. Plasma coal conversion technologies are characterized by a small time of reagents retention in the reactor and a high rate of the original substances conversion to the target products without catalysts. Thermochemical treatment of fuel for combustion is performed in a plasma fuel system, representing a reaction chamber with a plasmatron, while other plasma fuel conversion technologies are performed in a combined plasmachemical reactor of 100 kW nominal power, in which the area of heat release from the electric arc is combined with the area of chemical reactions.

This paper presents a numerical analysis and experimental investigation of two very different solid fuels: low-rank bituminous coal with 40% ash content and petrocoke with 3% ash content, gasification under steam and air plasma conditions with the aim of producing a synthesis gas. The numerical analysis was fulfilled using the software package TERRA for equilibrium computation. Using the results of numerical simulation, experiments on plasma steam gasification of the petrocoke and air and steam gasification of coal were conducted in an original installation. The nominal power of the plasma installation is 100 kWe and the total consumption of reagents is up to 20 kg/h. A high-quality synthesis gas was produced in the experiments on plasma gasification of solid fuels. It has been found that the synthesis gas content at about 97.4 vol.% can be produced. Comparison of the numerical and experimental results showed satisfactory agreement.
