Selective catalytic reduction catalyst
Industrial Denitration SCR catalyst called SCR flue gas denitration catalyst, SCR technology is denitration catalyst in the appropriate temperature, using ammonia (NH3) as the reducing agent, take the advantage of the reducing agent selective, perferentially reaction which industrial flue gas of nitrogen oxide (NOx) ,NOx is converted into no polluction of nitrogen and water, and NOx reduction efficiency is as high as above 90%.
Thereby reducing NOx emissions ,and reducing smoke pollution to the environment .SCR denitration technology has become the mainstream technology of flue gas denitrification in the world. We also supply Catalytic Converter, Catalytic muffler, Motorcycle catalytic converter, DOC Catalyst, Diesel Particulate Filters, DPF, SCR catalyst ,Ceramic honeycomb monolith , Metal honeycomb carrier, ect. Our management system has been certified the ISO9001 and TS16949 by SGS company.
At present , the commercial SCR catalysts are basically using TiO2 as base material and V2O5 as the main active ingredient ,with WO3 and MoO3 as anti-oxidation and anti-poisoning auxiliary components.
There are three types of SCR catalysts in the market, honeycomb catalyst, plate-types catalyst and corrugated catalyst. Commonly used is the honeycomb catalyst,
