The characteristics of product

At present, the SCR commercial catalyst which is based on the material of TiO2, is mainly used for producing denitration catalyst, which has the characteristics of big specific surface area, high catalytic activity, stable chemical property, good sulfur tolerant and long adsorption capacity. And as the carrier material of SCR denitration catalyst, titanium tungsten powder has good hydrophilicity, strong adsorption capacity, big specific surface area, high catalytic activity, stable specific surface after sintering at the high temperature of 400℃, and has not secondary pollution. Ttanium tungsten powder is mainly used for denitration with more than 95% denitration rate in the 100% gas condition.

Application fields

Titanium tungsten powder is mainly used for producing denitration catalysts which are used for the denitration treatment of boiler flue gas from power plant, chemical, petroleum refining, coking and glass manufacture plant; and the denitration treatment of exhaust from cars and steamships.
