In the SCR reaction, substances that promote the selective chemical reaction of reducing agents with nitrogen oxides in flue gas at a certain temperature. The catalyst is the core part of the SCR technology, which determines the denitration efficiency and economy of the SCR system. During operation, the SCR denitration catalyst will lose its activity due to physical or chemical factors and cannot carry out the catalytic effect.
