  • Vanadium/titania catalyst comprising natural manganese ore for removing nitrogen oxides and dioxin in wide operating temperature range and method of using the same
    Patent number: 8685882
    Abstract: 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, and a method for removing nitrogen oxides and dioxin over 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.

    Publication number: 20090142242
    Abstract: 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.
