[0002] The denitration catalyst plays a vital role in the selective catalytic reduction technology, and its main function is to reduce the ammonia oxygen compounds in the flue gas to harmless ammonia and water by accelerating the chemical reaction, thereby reducing air pollution. The denitration catalyst is usually used in the SCR denitration system of the power plant, and the SCR technology is the most mature flue gas denitration technology at present, which has the advantages of high efficiency and cost-effectiveness. The denitration catalyst provides appropriate temperature conditions to promote the reaction of the reducing agent and the ammonia oxygen compounds in the flue gas.

[0003] The denitration catalyst is also widely used in glass kiln, coal-fired industrial boiler, sintering furnace and incinerator applications.
