Abstract

The escalating proportions of nitrogen oxides (NO_x) and chlorinated volatile organic compounds (CVOCs) emissions from industrial flue gas have caused widespread concern. Presently, NH₃-SCR technology has attained widespread industrial application. The synergistic removal of NO_x and CVOCs within denitrification equipment is a promising and practical technology. However, in practical industrial emissions, complex components in flue gas will negatively affect the synergistic removal of NO_x and CVOCs. In this paper, the characteristics of NH₃-SCR and CVOCs catalytic oxidation reaction systems were systematically summarized separately, and the reciprocal interaction mechanism of the two reaction systems in the synergistic collaborative removal of NO_x/CVOCs was discussed in detail. In addition, it conducts a multifaceted analysis to outline the impacts of additional gas constituents (SO₂, heavy metals, HCl) in complex environmental settings on the NO_x/CVOCs co-abatement process. Furthermore, the method of designing the catalyst to obtain the appropriate surface properties by adjusting the electron structure and electron conductivity is introduced. In conclusion, the study delineates its limitations and proposes avenues for future research development. It is envisaged that this review can bridge the gap between the development of catalysts for the synergistic removal of NO_x/CVOCs and the practical imperatives, thus furnishing invaluable insights for industrial implementation.
