Rare earth element - tungsten trioxide SCR denitration catalyst can be applied to coal-fired power, glass, cement, steel mills plants, heating boiler room and other coal, oil, SCR flue gas denitration process. At the same time, because of this tungsten trioxide SCR catalyst belongs to rare earth system, which has many excellent properties, such as non-toxic, no need to recover, no fear for water, can be regenerated for several times, also it can be made into honeycomb, plate and corrugated and other types. This type of SCR denitration catalyst maybe possible fully replaces the imported VW-Ti system SCR catalyst technology in the near future.

 

Compares to ordinary V-W-Ti system catalyst, this cerium rare earth element tungsten trioxide denitration catalyst has many advantages:

1. None toxic effects, do not cause harm to humans and the environment;

2. Efficiency with long life

Experiments show that the catalytic ability of rare earth elements is higher than vanadium (V) element, thus brings the titanium dioxide, tungsten trioxide and other components reduced, so that the production costs reduced at the same time. Meanwhile, the increasing content of alumina also bring catalyst stiffness and hardness markedly improved, thus make the catalyst has longer life and better suit for glass furnace, cement, coal boiler other severer operating conditions with high ash content in flue gas;

3.Temperature window broaden, the minimum working temperature of this rare earth cerium-tungsten trioxide SCR denitration catalyst is as low as 260℃, which is 50℃ lower than the average 310℃, making the use scope expanded;

4. Can be regeneration more times, this kind of rare earth element catalyst is able to withstand repeated washing without damaged which means higher regeneration ability, it also greatly reducing the cost and realizing the goal of economic interests.
