Different processes have been proposed particularly for exhaust gas purification of pollutants, particularly from internal combustion engines or other machines operated with fossil fuels. According to the invention, the exhaust gas (GF) containing the pollutants flows through a reactor volume charged with non-thermal gas emissions and is thereby brought into contact- at least one time, preferably several times- with a solid reducing (RM). This reducing agent can particularly consist of carbon fibers. A suitable device for combining dialectrically-inhibited discharges with the reduction of the gas emissions has means (10) for field magnification in the reactor which are at largely periodic intervals.
