GB/T 39703-2020

This standard provides specific testing procedures and performance evaluation methods for corrugated plate-type DeNOx catalysts used in selective catalytic reduction (SCR) systems. It is primarily applied in the chemical and environmental protection industries, particularly for quality control and acceptance testing of catalysts employed in flue gas denitrification processes at power plants and industrial boilers. The guideline ensures consistent measurement of key parameters such as catalytic activity, mechanical strength, and chemical durability under standardized laboratory conditions.
