According to the present invention, the method of irradiating exhaust gas with an electron beam can be performed in a more spatial and energy efficient manner. The exhaust gas containing nitrogen oxides (NO x ) is irradiated with an electron beam to form a by-product, and then separated, while the exhaust gas thus treated is discharged into the atmosphere. Temporal and spatial pulses in the electron beam generator, with pulse frequencies and durations ranging from 10 Hz to 100 Hz and 10 -8 to 10 -5 seconds, respectively, while non-irradiation ranges from 10 -5 to 10 -1 seconds It provides an electron beam irradiation method characterized in that the electron beam is generated as possible. |
