The work is aimed at the development of a new environmentally appropriated process of
waste (including those hazardous and detrimental) conversion into a liquid product – the
high-quality combustible synthesis gas, and specifically at the increase of the process
energy efficiency with minimum emission of harmful substances

A new approach for production of synthesis gas:
The OES diagnosis reveals that CO+ ion and CH radical are present in the
plasma and the variation trend of their intensities is, to some degree, in
accordance with the variation trend of CO content in the gas, indicating that the
CO+ ion and CH radical are the precursors or origins of CO species in the gas.
