中文摘要:

理解苍蝇灰和水银的相互作用,在单个烟道气体作文的水银氧化的系统的实验在一个固定的床反应堆系统,解吸附作用率和水银的种形成上被进行是 valuated。结果显示苍蝇灰本身能显著地支持元素的水银氧化。苍蝇灰的一个分类激活地点在吸附解吸附作用测试期间根据水银的种形成被开发,由苍蝇灰的水银氧化的反应机制被建议。酸气体能支持水银氧化并且改进氧化产品的稳定性。格子氧是水银氧化的重要氧化剂。

英文摘要:

To understand the interaction of fly ash and mercury, systematic experiments on mercury oxidation in single flue gas composition are conducted on a fixed bed reactor system, the desorption rate and speciation of mercury are valuated. The results indicate that fly ash itself can significantly promote elemental mercury oxidation. A classification of fly ash activated sites is developed ac- cording to the speciation of mercury during adsorption-desorption tests, the reaction mechanism of mercury oxidation by fly ash is proposed. Acid gas can promote mercury oxidation and improve the stability of oxidation product. Lattice oxygen is an important oxidant of mercury oxidation.
