CATALYST AND METHOD FOR REMOVING NOX FROM COMBUSTION EXHAUST GAS
Provided is a catalyst for removing NOx from a combustion exhaust gas, in particular, a low-NOx combustion exhaust gas, wherein the catalyst has a ratio of a pore volume in a range of not less than 500 Å and not more than 3000 Å in a pore diameter relative to a total pore volume of not less than 15%...

Zusammenfassung: | Provided is a catalyst for removing NOx from a combustion exhaust gas, in particular, a low-NOx combustion exhaust gas, wherein the catalyst has a ratio of a pore volume in a range of not less than 500 Å and not more than 3000 Å in a pore diameter relative to a total pore volume of not less than 15% and not more than 40% and preferably a ratio of a pore volume in a range of not less than 1000 Å in the pore diameter relative to the total pore volume of not less than 10% and not more than 45% in a pore volume distribution in a range of not more than 105 Å in the pore diameter, and where SILICA is unlikely to be deposited and even when the amount of SILICA deposited is increased, denitration performance is hardly lowered. |
