Brief presentation of the institution

 Researchers of the Laboratory of Plasma Processing have over 40 years of experience working in different fields of development, scientific research and application of atmospheric and reduced pressure plasma and are able to successfully simulate new plasma technologies, using plasma equipment, designed in the Laboratory. Different composition gas and its mixtures are used for plasma jets formation.

 
Main research areas of the laboratory: 
 
–     development and research of DC plasma sources for wide range of applications;
–     research of processes and phenomena taking place in discharge channels, exhaust plasma jets and flows;
–     diagnostics of plasma and high-temperature flow and development of diagnostic measures;
–     research on interaction of plasma jets and substances in various plasma-technological processes;
–     research and implementation of plasma neutralization process of hazardous substances;
–     synthesis of catalytic and tribological coatings in plasma ambient and analysis of their properties;
–     research of thermal and heterogeneous processes for reacting product flowing around catalytic surface;
–     formation and modification of constructional material surfaces in plasma;
–     synthesis of micro- and nano- dispersed granules and mineral fiber from hardly meltable materials and analysis of their properties;
–     generation of water vapor plasma and its application for fuel conversion and neutralization of hazardous waste.

Main Plasma with liquids related topics

Rational exploitation of natural resources and environment protection from pollution by industries, household, medical waste are important tasks of the contemporary industry; it is likewise important to search for alternative energy resources. Decomposition of different types waste with water vapour plasma method, due to unique plasma properties, it is characterized as an extremely environmentally friendly process. 

At high temperature, water vapor decomposes into oxygen, hydrogen and their compounds, which react in plasma-chemical reactions. Extremely rapid chemical processes occur in water vapor plasma, when reactive elements H and O are formed. Due to this flow property, hydrocarbons introduced into water vapor plasma are decomposed very efficiently. This technology may be applied for decomposition of waste and environmentally hazardous materials or turn them into synthetic gas (CO + H2) during the conversion.

Various experiments of organic material decomposition were carried out. Chosen gaseous substances – hydrocarbons, liquid materials – toluene, glycerol, and solid materials – wood granules were introduced into the plasma-chemical reactor to perform the conversion.
