摘　　要：针对“双碳”背景下燃煤耦合可再生燃料烟气中多污染物(NO、Hg0及VOCs等)协同催化脱除问题,文章综述了单一组分及多污染物协同催化脱除机理、相互作用机制和催化剂设计开发的研究现状。指出多污染物协同脱除机理与单一污染物脱除机理类似,但协同脱除性能受污染物交互影响及烟气组分影响。着重从催化剂活性组分、非均相催化反应过程、整体式等方面综述了多污染物协同脱除催化剂研究进展。最后对多污染物协同催化脱除未来研究提出展望,指出进一步在分子和介观层次上优化,实现活性组分的高稳定性分散以兼济催化剂的活性和稳定性、打破反应物在催化剂表面的吸附方式、加强抗中毒设计以及在实际应用环境下的系统研究,将是燃煤耦合可再生燃料烟气多污染物协同脱除催化剂的重点发展方向。Aiming at the problems of synergistic catalytic elimination of multiple pollutants(NO,Hg0,VOC,etc.)in the flue gas of coal combustion coupled with renewable fuels under the background of“dual carbon”,we summarized the single component and multi pollutant synergistic catalytic elimination mechanism,interaction mechanism and catalyst design in this work.The mechanism of synergistic catalytic elimination of multiple pollutant is similar to that of single pollutant removal,but the performance of synergistic elimination is affected by interaction of pollutants and flue gas composition.The active components,heterogeneous reaction processes,and monolithic catalyst were reviewed.Finally,the prospect of synergistic catalytic elimination of multiple pollutants in flue gas of coal combustion coupled with renewable fuels is proposed that includes the catalyst optimization at the molecular and mesoscopic levels,high stability dispersion of active components,breaking the adsorption mode,design of anti-poisoning catalyst and systematic research in practical application.
