Abstract: The demand of power plant for DeNO_x catalysts has been rising dramatically high over the recent years. However, due to the late start of the manufacturing and application of SCR catalysts in China, the establishment of corresponding standards is also lagged behind. On the basis of the corresponding standards of Europe and the United States, the first product standard GB/T 31584—2015 of plate-type DeNO_x catalyst in China was published in 2015. In order to help the catalyst manufacturers, power plants and independent product testing organizations to better implement and apply this standard, the current situations of the main product standards and testing method standards for DeNO_x catalysts both in China and abroad are introduced. Meanwhile the key technical contents of the newly issued standard Plate-type DeNO_x catalysts (GB/T 31584—2015) are interpreted.

Key words: DeNOx, SCR catalyst, plate-type, standard, specification
