The selective catalytic reduction catalyst is a key part of the exhaust gas after-treatment system of diesel vehicles. Its function is to reduce and convert the NOx components in the exhaust gas to meet the corresponding emission standards.inquiry
For the treatment of nitrogen oxides emitted by diesel vehicles, the market mainly adopts selective catalytic reduction (SCR) technology, the core of which is the catalyst.
The combination of SCR catalyst and car urea can effectively eliminate exhaust pollutants and black smoke particulate pollutants.
The SCR catalyst mainly converts nitrogen oxides (NOx) in the engine exhaust into nitrogen and water to reduce NOx emissions. In a high-temperature environment, the urea injection unit injects an aqueous urea solution (a urea aqueous solution with a urea concentration of 32.5%) into the exhaust pipe. The urea liberates ammonia from the water at a high temperature. The ammonia is combined with the nitrogen in the exhaust gas in the SCR catalyst. The oxides react to produce nitrogen and water. SCR catalyst is by far the most effective means to reduce nitrogen oxide content.
