Oxidation of gaseous styrene by electron beam irradiation
چکیده انگلیسی

In this research, the absorbed dose, background gases, relative humidity, and initial concentrations were selected as control factors to discover decomposition characteristics of styrene using electron beam irradiation. It was confirmed that a considerable amount of styrene was removed by primary electrons as well as radicals and ions, which were produced after the electron beam irradiation. Moreover, the removal efficiencies of styrene were observed to rise when the initial concentration was lower, moisture content was higher, and the absorbed dose increased. For instance, 50 ppmv styrene showed extremely high removal efficiency (over 98%) at a condition of 2.5 kGy. A small amount of styrene oxide, benzaldehyde, aerosol, CO, and CO2 were produced as by-products after EB irradiation.


► To discover decomposition characteristics of styrene using an electron beam.
► 50 ppmv styrene showed extremely high control efficiency (over 98%) at 2.5 kGy.
► A small amount of styrene oxide and benzaldehyde were confirmed to be produced.
► Styrene with the vinyl group is readily decomposed compared to other VOCs.
