含氯挥发性有机物催化氧化反应过程中是否会生成二恶英一直是限制催化氧化技术应用的瓶颈与关键科学问题。项目针对含氯有机污染物催化燃烧过程中二恶英生成可能性开展研究，选取基础研究和工业应用涉及的催化氧化材料和含氯挥发性有机物，在不同反应条件下，研究分析催化氧化反应过程中间产物、副产物和中间物种种类及其分布，探究不同催化剂和反应条件下二恶英生成可能性，研究含氯有机物催化反应转化过程，揭示有机氯物种向多氯有机物转化过程中氯的集聚规律及其影响因素，探索抑制多氯有机化合物生成与反应的机制，在含氯挥发有机物催化氧化过程中是否会生成二恶英方面获得比较清晰的实验证据，为含氯挥发有机物催化氧化基础研究提供新认识，为控制技术应用提供技术支撑。

The possibility of dioxins formation is the key scientific problem in the catalytic oxidation process of chlorinated volatile organic compounds. This project aims at dioxins formation possibility in the process of chlorinated volatile organic compounds catalytic oxidation. The main research contents contain: (a) detection of dioxins (PCDD/Fs) in the catalytic oxidation of chlorinated volatile organic compounds; (b) analysis of the intermediate species and byproducts under different reaction conditions; (c) elucidation of Cl species transfer and transformation, and polychlorinated organic compounds formation and inhibition mechanism. The implementation of this project will provide scientific understanding of dioxins formation in the catalytic oxidation of chlorinated volatile organic compounds and technical support for the catalytic combustion technology.
