Furthermore, as a result of the catalyst being used in removing nitrogen oxides from exhaust gas, the removal rate of nitrogen oxides can be substantially improved.
The NOx occlusion/reduction catalysts hence have the improved ability to remove NOx after a durability test.
The invention pertains to the techniques for removing nitrogen oxides (NOx) contained in the exhaust gas discharged from boilers or the like.
The present invention relates to a catalyst for removing nitrogen oxides from exhaust gas, a preparation method thereof, and a method for removing nitrogen oxides from exhaust gas using the same.
A process for the removal of nitrogen oxides from waste gases is provided using a two-stage catalytic reactor scheme where the molar ratio of ammonia to nitrogen oxides is greater than 1.3:1.
