Catalyst for reducing nitrogen oxides and process for reducing nitrogen oxides |
| abstract |
A first catalyst for reducing nitrogen oxides comprising a crystalline silicate containing an iron in β-framework structure wherein a SiO 2 /Fe 2 O 3 mol ratio is 20-300 and at least 80% of the contained iron is an isolated iron ion Fe 3+ . A second catalyst for reducing nitrogen oxides comprising a crystalline silicate containing an iron in β-framework structure wherein a SiO 2 /Fe 2 O 3 mol ratio is 20-300 and log(SiO 2 /Al 2 O 3 ) by mol is at least 2. A predominant part of the contained iron is isolated iron ion Fe 3+ and at least a part thereof preferably has a tetrahedral coordination. These catalysts have high hydrothermal stability and exhibit enhanced activity for reducing nitrogen oxides by a reaction with a reducing agent such as ammonia, urea or an organic amine in a broad temperature range between lower temperature and higher temperature. |
