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 … See more 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 … See more 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 urea), is injected and mixed with the gases. The chemical equation for a stoichiometric reaction … See more 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. In general, the SCR unit is located … See more • Acid rain • Catalytic converter, which also catalyzes NOx conversion but does not use urea or ammonia See more Several nitrogen-bearing reductants are currently used in SCR applications including anhydrous ammonia, aqueous ammonia or … See more Most catalysts are given a finite service life due to known amounts of contaminants in the untreated gas.
