Kinetics and Thermodynamics of Four Toxic Metals in Coal Combustion and Incineration

PI建议研究As， Sb， Se和Hg这四种有毒金属的燃烧化学性质，它们的存在可能与煤燃烧和焚化炉废水有关。利用激光诱导荧光和发射光谱技术，从种子H2/O2/N2或H2/O2/Ar平面预混火焰中获得这些金属的原子、氧化物和氯化物的测量剖面，他计划推断出它们的分布，以及含有这些金属的其他可能未知物种的分布，这些分布是温度的函数。这些信息可以导致相关的热化学数据，如这些物种的键能和形成热，目前还没有可靠的数据存在，以及涉及这些物种动力学的机制见解。

Abstract Schofield CTS-9503660 The PI proposes to investigate the combustion chemistries of As, Sb, Se, and Hg, four toxic metals, whose presence can be of concern in coal combustion and incinerator effluents. From the measured profiles of the atoms, oxides, and chlorides of these metals obtained from seeded H2/O2/N2 or H2/O2/Ar flat premixed flames using laser induced fluorescence and emission spectroscopic techniques, he plans to deduce their distributions and those of other possible unidentified species containing these metals as a function of temperature. This information can lead to relevant thermochemical data such as bond energies and heats of formation for these species fop which no reliable data presently exists and to mechanistic insights involving the kinetics of these species.
