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

斯科菲尔德CTS-9503660国际和平研究所建议研究As、Sb、Se和Hg这四种有毒金属的燃烧化学，它们在燃煤和焚烧废气中的存在可能是令人担忧的。他计划根据激光诱导荧光和发射光谱技术从播种的H2/O2/N2或H2/O2/Ar平板预混火焰中获得的这些金属的原子、氧化物和氯化物的分布情况，推断它们的分布以及其他可能包含这些金属的未知物种的分布随温度的变化。这些信息可以导致相关的热化学数据，例如这些物种的键能和生成热，而目前还没有可靠的数据，并导致涉及这些物种动力学的机制洞察。

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.
