Decomposition Of Benzene By A Low Pressure Glow Discharge

Abstract

Decomposition characteristics of diluted benzene with nitrogen in a low pressure DC glow discharge plasma are investigated by emission spectroscopy, mass spectrometry, infrared absorption spectroscopy, concentration measurement and gas pressure monitoring. It is likely that benzene is decomposed chiefly by electron collision, and that excite molecules of nitrogen and/or nitrogen ions do not make a large contribution to benzene destruction directly. It is found that H, H2, H3, C, CH, CH4, NH3, C2, C2H, CN, C2H2, and C2H4 are produced in the glow discharge.
