Energy of low-temperature plasma in the processes of thermal conversions of carbon-containing medium

Abstract

One alternative for solving negative environmental impact is to use alternative renewable energy sources. However, technology is evolving and nowadays it cannot meet the needs of emerging economies. A promising direction in the field of clean technologies is the preliminary preparation of carbon-containing media of various origins by thermoconverting them into a gaseous state in high temperature fields. The analysis of the existing autothermal and allottermic technologies of gasification of carbonaceous media is given in the work. The advantages of allottermic technologies of high-temperature transformations under the action of arc plasma with steam oxidizing medium are presented. This method includes plasma formation processes, which combine in time and space thermal transformations and the generation of oxidant from water. The results of theoretical studies of the carbon-containing media plasma transformation process is presented in the article. The regularities of the temperature of steam-plasma transformation process influence on the qualitative and quantitative indicators of the obtained gas phase taking into account the medium elemental composition are established. Comparison of the cost indicators of production of synthetic motor fuel from natural gas by the known companies and from coal by steam-plasma conversion to gas is carried out.
