Use of carbon dioxide in the chemical synthesis technologies, plasma gasification and carbon production

Abstract

The modern electric power sector is based on burning of carbonaceous substances (coal, oil, natural gas, etc.). Large power stations are powerful local sources of carbon dioxide. Inconstancy of the electric power demand leads to increase in CO2 specific emissions, as the output power is basically higher than required one by the power network. One of promising ways of increase of operating efficiency of power stations is use of surpluses of the generated electric power in plasma technologies. The paper deals with the opportunity to use the plasma technologies in processes of methanol and methane production from carbon dioxide. Comparison of ranges of key parameters of plasma gasification of wood by air, carbon dioxide, and steam is presented. Also, use of CO2 for pure carbon production is examined.
