| titleOfInvention | Catalyst and method for clarifying exhaust gas |
| abstract | Using a proton-type? Zeolite as a catalyst, an excess of oxygen exhaust gas is brought into contact with the catalyst in the presence of methanol and / or dimethyl ether as a reducing agent to reduce and remove nitrogen oxides NO x in the exhaust gas. Proton type β zeolite, SiO 2 / Al 2 O 3 is preferred that the molar ratio is between 20 and 70. As a result, it has an excellent removing performance and the durability of the NO X even in exhaust gas containing oxides of sulfur, not even at a relatively low temperature of about the exhaust gas temperature is 300-400 ℃ the denitration performance. |
