抄録

A new flue gas treatment device using a pulsed high current electron beam in combination with a photocatalyst (TiO₂) was investigated. When the pulsed electron beam (100 keV, 120 A, 1 μs and 4.7 J/pulse) was injected into the gas chamber with a TiO₂ sheet on the inner wall, NO_x in a 5% oxygen mixed NO (= 200 ppm)/N₂ gas was removed with the energy efficiency of removal as high as 1010 nmol/J at a removal ratio of 83%, in which the amount of NO_x removed in 10 min without any radiation, about 25% of the initial NO concentration, was not included in the energy efficiency calculation. The concentration of NO₂ was below about 3 ppm in this process, which was a significant characteristic of NO_x removal in this device. When the flowing 4% oxygen mixed NO (= 200 ppm)/N₂ gas at a flow rate 1.4 L/min was irradiated by successive pulses of the electron beam, the energy efficiency of removal of 864 nmol/J at the removal ratio of 41% was obtained.
