Abstract

A study on the electron beam(E-Beam) decompositions of volatile organic compounds(VOCs) under background gases(helium, nitrogen, oxygen, air) has been carried out. Hexane selected as aliphatic VOCs was irradiated with electron beam using a batch reactor in the dose range of $0{\sim}10kGy$ and at ambient temperature. The concentrations of Hexane were 140 ppmC, 300 ppmC and 600 ppmC, respectively. Irradiation treatment efficiency of Hexane was evaluated by the GC/FID, GC/MSD, and the by-products were analyzed by $CO/CO_2\;and\;O_3$ analyzers. In different concentration, the maximum degrees of Hexane decomposition at 10 kGy were 96.4%(140 ppmC), 88.3%(300 ppmC), and 49.9%(600 ppmC). It was found that the decomposition efficiency of Hexane was higher than that of toluene at the same conditions(140 ppmC). In addition, the formation of acetone, benzene, 2-hexanone, and 3-hexanone were observed after the treatment of Hexane.
