“…Addition of 30 ppm n-butane caused a positive effect on the DPE decomposition efficiency by 6-10% at 9.8 kGy both in dry and humid conditions. Similar effect has been reported with respect to the removal of NO in combustion chemistry [27], pulsed corona discharge processing [28] as well as e-beam processing [29]. As was reported by Atkinson, additional radicals such as alkyl radical, alkoxy radicals, HO 2 and OH are produced during the decomposition of n-butane [30].…”

Decomposition of gas-phase diphenylether (DPE) in the order of several parts per million by volume (ppmv) was studied as a model compound of dioxin using a flow-type electron-beam reactor at an elevated temperature of 473 K. The ground state oxygen ( 3 P) atoms played an important role in the decomposition of DPE resulting in the formation of 1,4-hydroquinone (HQ) as a major ring retaining product. The high yield of hydroquinone indicated that the breakage of ether bond (C-O) is important in the initial step of DPE decomposition. Ring cleavage products were CO and CO 2 , and NO 2 was also produced from background N 2 -O 2 . The sum of the yields of HQ, CO 2 and CO accounts for over 90% of the removed DPE. Hydroxyl radicals (OH) were less important in the dilute DPE decomposition at a high water content, and were mostly consumed by recombination reactions to form hydrogen peroxide. The smaller the initial DPE concentrations, the higher the decomposition efficiency and the lower the yields of primary products. NO scavenges oxygen atoms and decreases the DPE decomposition, while the addition of n-butane causes positive effect on the decomposition of DPE due to the several secondary radicals (HO 2 , alkyl and alkoxy radicals) produced during the decomposition of n-butane.

“…Electron beam treatment of flue gases has been the subject of research in Japan, the USA, Germany, and Russia since 1970 (26,27,28,29). Electron beam irradiation of flue gases has shown simultaneous removal of more than 94% of SO2 and 80% of the NO x in tests in Japan (30).…”

The technology base formed by the development of high peak power simulators, laser drivers, free electron lasers (FEL's), and Inertial Confinement Fusion (ICF) drivers from the early 60's through the late 80's is being extended to high average power short-pulse machines with the capabilities of performing new roles in environmental cleanup applications and in supporting new types of industrial manufacturing processes. Some of these processes will require very high average beam power levels of hundreds of kilowatts to perhaps megawatts. In this paper we briefly discuss new technology capabilities and then concentrate on specific application areas that may benefit from the high specific energies and high average powers attainable with short-pulse machines. 011O5 1993 DtSTBIBU'I'ION OF THIS L._,..:I C,UME:NT IS UNLIMIFED OSTI ¢ ! such as the use of ethylene oxide or methyl bromide, which may, in turn, make accelerator treatment methods more appealing.
