Removal of NOX by pulsed, intense relativistic electron beam in distant gas chamber

Removal of NOX has been studied using a pulsed, intense relativistic electron beam (IREB). The dependence of NOX concentration and the removal efficiency of NOX on the number of IREB shot have been investigated within a distant gas chamber spatially isolated from the electron beam source. The distant gas chamber is filled up with a dry-air-balanced NO gas mixture with the pressure of 270 kPa, and is irradiated by the IREB (2 MeV, 30 A, 35 ns) passing through a 1.6-m-long atmosphere. With the initial NO concentration of 88 ppm, ∼ 70 % of NOX is successfully removed by firing 10 shots of IREB. The NOX removal efficiency has been found to be 50–155 g/kWh.
