摘要:
Disclosed is a vanadium/titania-based catalyst including natural manganese ore for removing nitrogen oxides and dioxin in a wide operating temperature range and a method of using the same. Specifically, this invention pertains to a vanadium/titania (V/TiO2)-based catalyst including natural manganese ore for removing nitrogen oxides and dioxin in a wide operating temperature range, in which the WTiO2 catalyst for selective catalytic reduction of nitrogen oxides and removal of dioxin contained in flue gas includes 5-30 wt % of natural manganese ore, thus exhibiting excellent activity of removing nitrogen oxides even in the low temperature range and of removing dioxin at the same time, and to a method of using the same. The catalyst of this invention has good thermal stability and thus can simultaneously manifest nitrogen oxides removal performance and dioxin removal performance superior to conventional vanadium/titania catalysts in a wide temperature range (150˜450° C.) including not only a high temperature range but also a low temperature range. As well, since unreacted ammonia emissions can be reduced, the formation of an ammonium salt is prevented and ammonium nitrate is decomposed at low temperatures, thus solving the problems of inactivation of the catalyst due to catalytic poisoning and of a shortened lifetime thereof, leading to economic benefits.
摘要:
Disclosed are a method for preparing a catalyst, which has excellent nitrogen oxide-removal performance and resistance over a wide temperature range, and the use of the catalyst. According to the disclosed method, the oxidation number and surface defects of the catalyst are changed by applying artificial high energy through mechanical ball milling during the preparation process of the catalyst, instead of applying the addition of a precious metal, the deformation of a support and the use of a co-catalyst in order to increase NOx removal activity, such that activation energy for inducing redox reactions can be decreased.
