Living in this extremely developed era in technology and industry, power plants, automobiles are fully around us. Thermal power plants cause very serious air pollution, besides, by the terms of chemical plants and factories, their exhaust emissions also make the air quality even worse. Determined to rectify the environment is not just a government thing, but more of the people's environmental awareness.

 

For example, the exhaust of car causes more serious environmental pollution along with civilian price. The ordinary people cannot control the oil quality upgrade, but can install SCR catalyst in the car exhaust pipe, thus to reduce urban pollution. Earlier developed precious metal catalyst is too expensive to be accepted by general public; fortunately, we have developed a non-noble metal catalysts and catalyst-frequency combustion through continuous research, such as tungsten trioxide SCR desulfurization catalyst, which maximize purifies sulfur dioxide and other harmful emissions.

 

In ten years from 1990~2011, thermal power generation capacity in China raised from 0.5 trillion kW•h to 2.7 trillion kW•h, which takes 82% of the average total electricity generation. By the time thermal power plants bring such a large amount of electricity, it also cause caused a huge burden to environment, so, it is imperative in managing thermal power plant flue exhaust. For incineration plants, non-precious metal catalysts are the first choice because of their huge consumption. These desulfurization catalysts are use titanium dioxides as framework materials, and the vanadium pentoxide as the main active ingredients. Tungsten trioxide as an active ingredient has been added to the desulfurization catalyst, since it has the property of anti-vulcanization and anti-poison, thereby to enhance the activity of the catalysts.
