The synergetic abatement of multi-pollutants is one of the development trends of flue gas pollution control technology, which is still in the initial stage and facing many challenges. We developed a V₂O₅/TiO₂ granular catalyst and established the kinetic model for the simultaneous removal of NO and chlorobenzene (i.e., an important precursor of dioxins). The granular catalyst synthesized using vanadyl acetylacetonate precursor showed good synergistic catalytic performance and stability. Although the SCR reaction of NO and the oxidation reaction of chlorobenzene mutually inhibited, the reaction order of each reaction was not considerably affected, and the pseudo-first-order reaction kinetics was still followed. The performance prediction of this work is of much value to the understanding and reasonable design of a catalytic system for multi-pollutants (i.e., NO and dioxins) emission control.

多种污染物的协同减排是烟气污染控制技术的发展趋势之一，目前仍处于起步阶段，面临诸多挑战。我们开发了V ₂ O ₅ / TiO ₂颗粒催化剂，并建立了同时去除NO和氯苯（即二恶英的重要前体）的动力学模型。用乙酰丙酮氧钒钒前驱体合成的颗粒催化剂具有良好的协同催化性能和稳定性。尽管NO的SCR反应和氯苯的氧化反应相互抑制，但各反应的反应顺序并没有受到很大影响，并且仍然遵循拟一级反应动力学。这项工作的性能预测对于理解和合理设计用于多种污染物（即NO和二恶英）排放控制的催化系统具有重要价值。
