Photoionization mass spectrometry of combustion radicals. Final technical report

PDF Version Also Available for Download.

Description

Fundamental research on the combustion of halogenated organic compounds with emphasis on reaction pathways leading to the formation of chlorinated organic compounds and the development of continuous emission monitoring methods will assist in DOE efforts in the management and control of hazardous chemical wastes. Selective laser ionization techniques are used in the laboratory for the measurement of concentration profiles of radical intermediates in chlorinated hydrocarbon flames. A novel flame-sampling VUV laser photoionization mass spectrometer, constructed with DOE funding, is in use for these studies. Progress is reported here on the use of this new facility in the development, refinement, and ... continued below

Description

Fundamental research on the combustion of halogenated organic compounds with emphasis on reaction pathways leading to the formation of chlorinated organic compounds and the development of continuous emission monitoring methods will assist in DOE efforts in the management and control of hazardous chemical wastes. Selective laser ionization techniques are used in the laboratory for the measurement of concentration profiles of radical intermediates in chlorinated hydrocarbon flames. A novel flame-sampling VUV laser photoionization mass spectrometer, constructed with DOE funding, is in use for these studies. Progress is reported here on the use of this new facility in the development, refinement, and verification of chemical kinetic models describing the thermal destruction of toxic chlorocarbons commonly found in chemical wastes. In the past two years the author has used the flame sampling VUV laser ionization mass spectrometer system for studies of chlorocarbon-doped methane/oxygen flames. Relative concentration profiles and photoionization efficiency curves have been measured for over two-dozen key reaction intermediates. Preliminary kinetic models have been developed that promise an improved understanding of chlorocarbon chemistry under laboratory flame conditions.
