氮氧化物和挥发性有机化合物协同净化催化剂研究进展
Advances in catalysts for cooperative removal of NOx and VOCs
摘要
Abstract
[Objective]Conventional flue gas treatment catalysts demonstrate insufficient catalytic performance under complex operating conditions,to address the need for synergistic removal of nitrogen oxides(NOx)and volatile organic compounds(VOCs)from biomass/solid waste co-combustion flue gases.Facing this technical challenge,there is an urgent requirement to develop advanced synergistic purification catalysts to meet practical application demands.[Methods]In this paper,the selective catalytic reduction of NOx,the catalytic oxidation of VOCs and their synergistic catalytic reaction mechanisms are reviewed,the interaction mechanisms between NOx and aliphatic compounds,aromatic compounds and heteroatom-containing compounds and the current status of catalysts are described,and the influence of the coupling mechanism of the redox sites and acidic sites on the reaction performance,selectivity and stability of the catalysts is elucidated.[Results](1)The co-purification of NOx and VOCs is mainly achieved through three catalytic pathways:the coupling of NH3-SCR with hydrocarbon oxidation reactions,selective catalytic reactions using NH3/HC mixed reducing agents,or hydrocarbon-SCR reactions.(2)Through rational catalyst design,researchers can precisely regulate the number and spatial arrangement of active sites while optimizing reaction pathways,thereby reducing byproduct generation and achieving superior synergistic catalytic performance.(3)Additionally,reaction conditions and reactant states significantly influence the synergistic catalytic performance,thereby providing critical technical pathway guidance for developing high-efficiency co-purification catalysts.[Conclusion]Catalyst performance depends on the synergistic modulation of acid sites and redox sites.Future studies may incorporate machine learning to optimize active site design for enhanced catalytic performance while developing synergistic catalysts with SO2/H2O poisoning resistance,thereby providing references for efficient co-purification of multi-pollutants(NOx,VOCs,etc.)in the power industry.关键词
