中文摘要：
在构建70步详细反应机理的基础上，通过敏感度分析、试验研究及动力学模拟对臭氧在烟气中氧化零价汞机理进行深入分析与探讨．敏感度分析表明，反应Hg＋NO3=NO2＋HgO是直接影响Hg°氧化的关键基元反应，NO3的生成量是影响Hg°氧化的最关键因素．试验研究与动力学模拟表明，臭氧在烟气中能有效氧化零价汞，ψ（O3）／ψ（NO）越大或烟气温度越高（所研究温度范围内），Hg°氧化效果越好，且都基本呈线性关系．分析其原因为，ψ（O3）／ψ（NO）增大或烟气温度升高，可提高NO3的生成量，而NO3生成量的提高可直接使Hg°氧化效果增强．动力学模拟与试验研究结果取得了很好地吻合，验证了所构建反应机理的正确性．
英文摘要：
A detailed chemical reaction mechanism including 70 steps of elemental mercury oxidization in flue gases by ozone was developed. Sensitivity analysis, experimental research and kinetic simulation were performed to analyze the oxidization mechanism. The sensitivity analysis results show that the reaction Hg＋ NO3 = NO2＋HgO is the key step and the NO3 concentration is the most important factor for affecting Hg° oxidization. The experimental research and kinetic simulation results indicate that Hg° oxidization increases linearly when the volume fraction ratio of O3 to NO becomes larger or the reaction temperature becomes higher. It could be explained by that, Hg° oxidization increases linearly with the increasing of the NO3 concentration, while the NO3 concentration increases linearly when the volume fraction ratio of 03 to NO becomes larger or the reaction temperature becomes higher. The kinetic simulation results accorded well with the experimental results, which indicated that the chemical reaction mechanism was reasonable.
