SCR denitration titanium tungsten powder is a kind of ideal catalyst support material, has the characteristics of typical porous structure and high heat stability, is the SCR denitration technology with carrier of catalyst and the key production of raw materials.
Selective catalytic reduction (SCR) denitrification technology is the most mature technology in denitrification industry at home and abroad, and the catalyst is the core of SCR denitration technology, which is the key factor of the whole system cost control. As the carrier of catalyst, titanium tungsten powder is the key raw material for the production of catalyst, accounting for 80%~90% of the catalyst, accounting for more than 60% of the total catalyst cost.
Titanium tungsten powder in the process of the denitration reaction, WO3 as a catalytic agent can improve the thermal stability of the titanium dioxide carrier, inhibit the sintering of titanium dioxide anatase type and rutile petrochemical, enhance the activity of catalyst, surface acidity, and can limit the oxidation of SO2.Therefore, tungsten-salt precursor is of great significance for improving the performance of titanium tungsten powder.
