The article presents a comprehensive plasma chemical technology for processing solid fuels, using examples of Turgai brown coal or lignite. Thermodynamic and experimental investigations of the technology were made. The technology allows producing synthesis gas from the coal organic mass and valuable components (technical silicon, ferrosilicon, aluminum, and carbon silicon) from the mineral mass. The thusly produced high-calorific synthesis gas can be used for synthesis of methanol, as a high-calorific reducing gas instead of blast-furnace coke as well as power gas for thermal power plants.
