Q: How do SCR systems work to reduce NOx from diesel engines? This program allows Mack dealers to recycle scrap emission cores, such as diesel particulate filters (DPFs) and diesel oxidation catalysts (DOCs). Using fully compliant process, Red Fox Resources purchases scrap/used emission control systems from the dealer and reclaims the catalyst material for re-use. Aftertreatment Selective Catalytic Reduction (SCR) Catalyst, Replacement, CHU, CXU, GU, TD Item Description Aftertreatment Selective Catalytic Reduction (SCR)Catalyst, Replacement, CHU, CXU, GU, TD View File Urea is used at a 32.5 % mixture with 67.5% DI water in DEFendal™ Diesel Exhaust Fluid in Selective Catalytic Reduction Systems (SCR). The fluid is in used to reduce the NOx pollutants, in exhaust gases from combustion from diesel, dual fuel, and lean-burn natural gas engines.
Catalysts SCR catalysts are made from various ceramic materials used as a carrier, 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. This in conjunction with the diesel catalytic converter results in several pounds per square inch of congestion and back pressure in your exhaust. Since adding the DPF to the exhaust system results in a reduction in fuel mileage, quite a few question the reason why the government chose to make this technology a requirement when it’s not even ...

Browse 16 used SCR Catalysts by Cummins, Paccar, Mack, Volvo, and more.Sep 01, 2018 · In SCR, NO x is converted into nitrogen and water by the reaction with ammonia over a special catalyst. Typically, the exhaust gas temperature at SCR inlet (referred to as SCR temperature hereinafter) needs to be at least 200 °C for a significant level of NO x conversion to occur (Slimarik et al., 2014; Cavataio et al., 2007).
