We manufacture catalyst in a number of different pitched.The choice of pitch is optimized after the study of the flue gas composition and the allowable pressure drop across the SCR reactor.
Typical industrial applications:
It is widely used inthermal power plants, coal-fired power plants, waste incineration plants, steel plants, fertilizer plants, nitric acid plants, cement plants, petrochemical chemical plants and other all industrial which need to reduce the NOx emissions, also used in diesel engines tail gas treatment etc..
Prone to alkali metal poisoning of denitrification catalyst
In addition to cement kilns and sintering machines in iron and steel plants, they are prone to alkali metal poisoning of denitration catalysts, including coking plants, alumina clinker kilns and biomass direct-fired power generation boilers. Therefore, the choice of denitration catalyst should fully consider the alkali toxicity and blocking resistance of the catalyst, and it is necessary to use a catalyst with better anti-clogging performance for denitration to smoothly discharge ash. At the same time, a reasonable choice of soot blower and soot blowing frequency to prevent soot accumulation and physical deactivation of the catalyst.

According to the customer's requirements, we can produce different pitch and formulations of honeycomb SCR de NOx catalyst.
Technology Introduction
SCR technology is a reaction at use of the denitration catalyst at a certain temperature (270-400℃),that NOX in the flue gas mixed with ammonia gas from the reducing agent supply system after the occurrence of the selective catalytic reduction reaction of nitrogen and water ,thereby reducing NOx emissions,and reducing smoke pollution to the environment .
Several reductants are currently used in SCR applications including anhydrous ammonia,aqueous ammonia(25%NH3)or use.Typical SCR system consist of anhydrous ammonia storage &transportation (using anhydrous ammonia as the reductant )evaporator ,AIG and mixer,flue gas system ,reactor and ammonia emergency management system.
Reaction:
4NO+4NH3+O2→4N2+6H2O, 2NO2+4NH3+O2→3N2+6H2O
The honeycomb SCR catalyst packaging
Carton box to pallet, wooden case or as per customer's requirements.
Certification：we passed ISO9001 ,ISO4001, SGS,CNAS and others
