A Study on SCR Catalyst Support

Abstract:

NO_x is one of the most serious atmosphere pollutants, and how to control and remove NO_x is the hot research in the environmental field all over the world. SCR is considered as one of the most effective denitration methods at present. In SCR technology, catalyst is the core of the SCR system, and the performance of SCR catalyst mainly depends on the active component and catalyst support. Catalyst support can not only affect the choice of the active material and the catalyst promoter, but also affect the flue gas denitration efficiency. This paper mainly introduces four kinds of SCR catalyst supports: TiO₂, Al₂O₃, activated carbon and activated carbon fiber and ZSM-5 zeolite. The performance of the four types of catalyst supports are compared, and SCR activity test of Mn-Ce supported and V₂O₅ supported on different catalyst supports are conducted respectively. Finally, for Mn-Ce supported and V₂O₅ supported catalysts, this paper puts forward that TiO₂ is the most widely used and effective catalyst support.
