Nonthermal plasma (NTP) at atmospheric pressure produces highly reactive radicals (O, OH, etc.) that promote chemical reactions to treat gaseous pollutants. Acid gases such as SOx, NOx and HCl, Greenhouse gases such as CO2
, NxOy and PFCs(perfluorocarbons), Ozone depletion substances such as freons and halon, Volatile organic compounds (VOCs) such as toluene,xylene, trichloro-ethylene (TCE), trichloro-ethane (TCA)and ethylene glycol monoethyl ether (EGM), toxic gases such as Hg and dioxins NTP could also be used for ozone production that used for water treatment NTP could also be used for syngas production from CO2
and natural; gas There are a variety of types of NTP reactors, such as DC corona discharge, pulsed corona discharge, dielectric barrier discharge (DBD), surface discharge, ferroelectric pellet packed-bed reactor, microwave, plasma jet, and gliding arc, etc that can be used as a source for.
