Abstract Fontijn 9632492 The proposed work represents an extension of the PIs current program to provide rate coefficient and mechanistic data for individual reactions of toxic metal species up to high temperatures which are of importance in incineration processes. In the previous work the reactions of Cu, Cr, Sn and Cd with oxidants such as N2O, O2 , Cl2, and HCl were investigated as a function of temperature using three unique types of apparatus. A semi- empirical configuration interaction (SECI) theory was also developed to help correlate the experimental results. The proposed program will extend the experimental effort to include reactions of Ni, Pb, Sb, and As in elemental, oxide and chloride forms with HCl, O2, CO2, and H2O, as a function of temperature, using the High Temperature Flow Reactor (HTFF), Metals High Temperature Photochemistry (MHTP) apparatus and a mass spectrometer HTFF combination. These studies will be complimented by further development of the semi-predictive theories SECI and MTST (metals transition state theory) in order to extend and compare with the experimental data.

摘要Fontijn 9632492拟议的工作代表了PIS现行程序的扩展，以提供有毒金属物种在高温以下的个别反应的速率系数和机理数据，这在焚烧过程中是重要的。在以前的工作中，用三种独特的装置研究了铜、铬、锡和镉与氧化剂N2O、O2、Cl2和HCl的反应随温度的变化。用半经验组态相互作用(SECI)理论对实验结果进行了关联。拟议的计划将扩大实验范围，利用高温流动反应堆(HTFF)、金属高温光化学(MHTP)设备和质谱仪HTFF组合，包括元素、氧化物和氯化物形式的Ni、Pb、Sb和As与HCl、O2、CO2和H2O的反应，作为温度的函数。这些研究将通过进一步发展半预测理论SECI和MTST(金属过渡态理论)来补充，以便扩展并与实验数据进行比较。
