Decomposition of benzene in the RF plasma environment. Part I. Formation of gaseous products and carbon depositions.
This study employed radio-frequency (RF) plasma for decomposing benzene (C6H6) gas, and examined both gaseous products and solid depositions after reaction. The reactants and products were analyzed mainly by using both an on-line Fourier transform infrared (FT-IR) spectrometer and a gas chromatography. The analyses for solid deposition included electron spectroscopy for chemical analysis (ESCA)...
متن کاملField detection of CO and CH4 by NIR 2f modulation laser spectroscopy
A novel compact fiber-coupled NIR system based on a DFB diode laser source is employed as a portable and sensitive gas sensor for trace detection of combustion pollutant molecules. We demonstrate the performance of such an NIR gas sensor by tracing the absorption lines of CO and CH4 using 2f-WMS technique at moderate temperature of T ~ 600°C in the recuperator channel of an industrial furnace...
متن کاملComparative Study Of Various Dissolved Gas Analysis Methods To Diagnose Transformer Faults
Dissolved gas analysis (DGA) is a reliable technique for detecting the presence of incipient fault conditions in oil immersed transformers. In this method the presence of certain key gases is monitored. The various analysis methods are : Rogers ratio, IEC ratio, Doernenburg, Duval triangle, key gas, artificial neural network (ANN) method. In this paper the various DGA methods are evaluated and ...
متن کاملFormation of simple organic molecules in inner T Tauri disks
Aims. We present time dependent chemical models for a dense and warm O-rich gas exposed to a strong far ultraviolet field aiming at exploring the formation of simple organic molecules in the inner regions of protoplanetary disks around T Tauri stars. Methods. An up-to-date chemical network is used to compute the evolution of molecular abundances. Reactions of H2 with small organic radicals such...
متن کاملAnalysis of Gases Dissolved in Electrical Insulating Oil by Gas Chromatography
1.1 This test method covers three procedures for extraction and measurement of gases dissolved in electrical insulating oil having a viscosity of 20 cSt (100 SUS) or less at 40°C (104°F), and the identification and determination of the individual component gases extracted. Other methods have been used to perform this analysis. 1.2 The individual component gases that may be identified and determ...
