The purpose of the SCR catalyst, Selective Catalytic Reduction catalyst, is a new technology that is suitable to effectively reduce nitrogen oxide (NOx) emissions in diesel engines. Its most important feature is providing a place for chemical reactions and so using the NOx as raw material to produce pure nitrogen compounds or nitrogen water. The SCR catalyst has three main technological points: 1) it has great thermal stability and can therefore work efficiently even under high temperatures; 2) the strongest build so far used by any such device, which makes for better wear resistance and longer life. Actively used today in automobile markets around the world (especially heavy vehicles and large engines), this catalyst helps meet the ever-more-strigent environmental standards. Its functions for emergencies In remote regions can depend on getting power Generation intermittent--and that means stymied environmental health efforts like stopping NOx emissions from industrial processes.
