ABSTRACT:
A method by which irradiation treatment of an exhaust gas with electron beams can be performed in a more space- and energy efficient manner. The method in which an exhaust gas containing nitrogen oxides (NOx) is irradiated with electron beams so as to form by-products, which are then separated whereas the treated exhaust gas is liberated into air atmosphere, characterized in that electron beams are generated in such a way that they have a pulsed temporal and spatial shape within an electron beam generator, with the pulse frequency and duration being in the respective ranges of 10 Hz-100 kHz and 10.sup.-8 -10.sup.-5 second whereas the non-irradiation region lasts for a time interval of 10.sup.-5 -10.sup.-1 second.
