Production Description
SCR catalyst is widely used in the De-NOx sustems of coal -FIred power plant, Gas-fired power plant. and oil-fired plant as well. Typical structure is honeycomb.
High performace honeycomb cayalyst
1. high activity. abrasion resistance
2.unique components based on flue-gas analysis, wide applications
3.high temperature products
4.harder material to ensure erosion resistance and lifetime
5.TiO2 base, high surface area per unit volume
6.Improved compositions, high resistance to poisoning
7.Wide applications, high durability

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 (270-400ºC),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
