The discharge using pulse power with a short pulse width can produce a lot of electrons with high energy. This method has a possibility to remove poisonous gases with low energy consumption. In this paper, the inductive energy storage pulsed power generator, which can generate narrow and high voltage pulses (FWHM less than 100ns, output voltage of about 100kV), is used to remove NOx gas. It is found from spectrum measurement that this generator can produce high energy electrons, more than 10eV, in the discharge region at atmospherics pressure. The mixed gases of NO and N2 are used as a trial gas. The NO removal ratio of about 95% is achieved without producing NO2. These chemical phenomena are approximately explained by solving rate equations.
