Catalytic Ceramic Candle Filter for Combination of Particulate Removal and Selective Catalytic Reduction of Nitrogen Oxides (SCR)

摘要

The present invention provides a catalyst for use in the selective catalytic reduction (SCR) of nitrogen oxides, comprising: · Ceramic candle filter base and a coating comprising a metal oxide carrier comprising titanium oxide and a catalytic metal oxide comprising vanadium oxide, wherein the mass ratio of vanadium/titanium is 0.03 to 0.27; The mass ratio is calculated based on the mass of vanadium metal and titanium metal, the catalyst comprises 1 to 20 wt % of catalytically active material, and the catalyst metal oxide is adsorbed on the surface of the metal oxide support.
