| titleOfInvention | A kind of Fe of tungsten oxide finishing 2o 3catalyst, preparation method and its usage |
| abstract | The present invention relates to a kind of Fe of tungsten oxide finishingn 2 on 3 catalyst, described catalyst has following chemical composition: WOn x / Fen 2 on 3 (x=2 ~ 3), described WOn x the mass percent accounting for described catalyst is 1 ~ 10wt.%.The invention also discloses the preparation method of above-mentioned catalyst.The Fe of surface unmodifiedn 2 on 3 material NHn 3 selective Catalytic Reduction of NOn x (NHn 3 -SCR) activity is extremely low, and operating temperature window is extremely narrow, and has a large amount of Nn 2 o accessory substance generates, and passes through WOn x after finishing, NHn 3 -SCR catalytic activity and Nn 2 generate selective all have very significantly improve, be suitable for very much stationary source and moving source NOn x catalytic removal. |
