Abstract :
Diesel-flue-gas treatment has been demonstrated by using an intense, pulsed relativistic electron beam (IREB). A flue gas treatment chamber, 1.6-m isolated from the IREB source, is filled up with the diesel flue gas with the pressure of 200 kPa, and is irradiated by IREB (2 MV, 0.12 kA, 65 ns (FWHM)). The maximum kinetic energy of IREB injected into the gas chamber is experimentally estimated to be -0.23 MeV. When the diesel flue gas is irradiated by firing 10 shots of the IREB, the concentration of NOx, SO2, and CO are decreased from 75, 14, and 770 ppm to 5, 11, and 690 ppm, respectively. It is found that - 93 % of NOx is removed by firing 10 shots of the IREB irradiation. We have obtained the energy efficiency of NOx removal of 256 g/kWh.
