Factory Supply Honeycomb SCR catalyst for Nox Reduction

Denitration in different industries is also being carried out one after another. The temperature, ash and alkali metal content of their flue gas are very different. The alkali content of flue gas in many industries is much higher than that of pulverized coal power generation denitrification. Therefore, it also poses a new challenge to the problem of alkali metal poisoning of the SCR vanadium-based denitration catalyst. Especially in industries such as cement kilns, iron and steel sintering machines, coking plants, alumina clinker kilns and biomass boilers, and high-alkali coal power generation, it is necessary to attach great importance to the poisoning risk of alkali metals in flue gas denitration to denitrification catalysts.

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

P84 Dust Filter Cloth
Dust Collector P84 Filtering Material
Long-term temperature resistance 230℃, instantaneous temperature resistance 260℃; It is made of a polycondensation polymer, which is not resistant to hydrolysis; the cross section is in the shape of a trilobe. Due to the increased surface area of the single fiber, it can effectively trap particles, and the filtration accuracy is high; It is a non-thermoplastic fiber, and has stronger abrasion resistance to pulse cleaning than glass fiber. Therefore, P84 can be used instead of glass fiber or mixed use under conditions that require good abrasion resistance. Its anti-oxidation performance is better than PPS filter media, but its acid resistance and hydrolysis resistance are slightly worse, and its alkali resistance is poor. It is suitable for use in the treatment of kiln flue gas with low sulfur content.
