At dilute pollutant concentrations less energy than incinerators or other thermal processes is sufficient to
treat the pollutants. Non-equilibrium plasma treatment of flue gas can achieve the cracking of such
hydrocarbon pollutants present in the gas stream. In general it can be stated that non equilibrium plasmas
use most of the discharge energy to produce and accelerate electrons. These electrons generate highly
reactive free radicals which can selectively decompose toxic compounds. This can be achieved at low gas
temperatures and at atmospheric pressure conditions that are of utmost importance for flue gas or off gas
treatment. A prominent feature is the simple scalability from small laboratory reactors to large industrial
installations. Industrial applications include ozone generation, pollution control and surface treatment.
This work gives idea about the use of non-thermal plasma to reform or dissociate carbon-hydrogen bonds
in hydrocarbons to obtain hydrogen and syn gas or to obtain methane as a product or to obtain various
lower hydrocarbons from the mixture of volatile organic compounds.
