Control factors and by-products during decomposition of butane in electron beam irradiation

Decomposition of sulfur compounds by radiolysis: I. Influential factors

“…To measure the absorbed dose in the reactors, a cellulose triacetate film dosimeter (FTR = 125, Fuji, Tokyo, Japan) and a UV/VIS spectrophotometer (UVikonxs, Secomam, Ales Gard, France) at a 280 nm wavelength were used. More detailed information regarding the reactors and absorbed doses can be found in previous publications [15,[21][22].…”

“…In particular, EB control technology is useful to contain low concentration and/or high flow rate emission sources at ambient air temperature and requires relatively little energy [13][14][15][16]. EB operation time is also quite short because electrons are generated during 10 À18 -10 À12 s and interact with the gas molecules.…”

Organic Pollutants Treatment from Air Using Electron Beam Generated Nonthermal Plasma – Overview

“…The initial concentration of chlorinated ethylene was in below 2000 ppm and the water concentration in the air mixture was 200-300 ppm. Son et al (2010a) studied decomposition of butane in EB irradiation in batch system, it was found that removal efficiencies of butane were 40% at 2.5 kGy and 66% at 10 kGy, when the initial concentration of butane was 60 ppm.…”

“…Different base gases influencing on the decomposition efficiency of butane were studied (Son et al, 2010a), it was found that decomposition efficiency of butane was extremely low when the background gas was He, in contrast to the efficiencies with background gases of N 2 and air. Decomposition efficiencies of butane was 23% in He, 63% in N 2 and 70% in air at 10 kGy absorbed dose.…”

“…Chloroacetyl chloride was not observed as degradation products, but it was a degradation product for 1,1-DCE (Sun et al, 2001). Son et al (2010a) studied butane decomposition under EB irradiation and identified CO 2 , acetaldehyde, acetone, 2,3-butandione, 2-butanone, and 2-butanedinitrile as degradation products of butane.…”
