Preliminary test in decomposition of styrene by electron beam treatment

This project is a continuation of the experiments with VOCs electron beam t reatment (Honkonen et al., 1997. Proc Int. Symp. on Radiation Technology fo r Conservation of the Environment, Zakopane, Poland, September, 1997). Expe rimental results of electron beam treatment of gaseous styrene under atmosp heric pressure are presented in the paper. Two irradiation doses of 10 and 20 kGy were applied. Analyses of irradiation products were performed with a gas chromatography-mass spectrometer. The results showed that main product s produced by irradiation were benzaldehyde and phenol. We observed those c ompounds both in the gas and solid/liquid phase. The removal efficiency of styrene front the gas phase ranges from 83 to 95%. In this work we focused on organic products of irradiated styrene. (C) 1999 Elsevier Science Ltd. A ll rights reserved.
