GB/T 38219-2019Testing standard of catalysts for flue gas denitration (English PDF)

1 Scope

This standard specifies the selectivity for the purification of nitrogen oxides from flue gases from coal, fuel, gas, garbage and biomass combustion.

Terms and definitions, test items, test methods, and test devices for catalytic reduction (SCR) catalysts.

This standard is applicable to honeycomb, flat, and clover-shaped catalysts used in industries such as steel, nonferrous metals, building materials, petrochemicals, and electric power.

Detection of new catalysts, used catalysts, and regenerated catalysts, corrugated, granular catalysts, and the like can be referred to.
