SCR catalysts are made from various porous ceramic materials used as a support, such as titanium oxide, and active catalytic components are usually either oxides of base metals (such as vanadium, molybdenum and tungsten), zeolites, or various precious metals. Another catalyst based on activated carbon was … Visa mer Selective catalytic reduction (SCR) is a means of converting nitrogen oxides, also referred to as NO x with the aid of a catalyst into diatomic nitrogen (N 2), and water (H 2O). A reductant, typically anhydrous ammonia (NH … Visa mer The NO x reduction reaction takes place as the gases pass through the catalyst chamber. Before entering the catalyst chamber ammonia, or other reductant (such as Visa mer Most catalysts are given a finite service life due to known amounts of contaminants in the untreated gas. The most notable complication is the formation of ammonium sulfate Visa mer History SCR was applied to trucks by Nissan Diesel Corporation, and the first practical product "Nissan Diesel Quon" was introduced in 2004 in Japan. In 2007, the United States Environmental Protection Agency (EPA) … Visa mer Several nitrogen-bearing reductants are currently used in SCR applications including anhydrous ammonia, aqueous ammonia or dissolved urea. All those three reductants are widely … Visa mer In power stations, the same basic technology is employed for removal of NO x from the flue gas of boilers used in power generation and industry.
