Science and Technology Daily (Reporter Zhang Jingyang, Correspondent Li Baole) The reporter learned from Baotou Rare Earth Research Institute on April 18 that part of the research and development results of the National Six Rare Earth Selective Catalytic Reduction (SCR) catalysts of the Rare Earth Catalytic Materials Research Group of the Institute have passed the National Automobile Quality Supervision and inspection center, Dongfang Commercial Vehicle and other third-party organizations for bench test certification.
"The National VI emission standard is currently one of the most stringent emission standards in the world, and the SCR aftertreatment system is a key part of the diesel exhaust aftertreatment system.
For the treatment of nitrogen oxides emitted by diesel vehicles, SCR technology is mainly used in the market, and the core is the catalyst.
Through several years of program improvement and experimental testing, Li Zhaoqiang’s research team has successfully developed a catalyst powder with excellent low-temperature activity and high-temperature stability.
The research group added a sufficient amount of rare earth components to the catalyst.
"It's like every car equipped with rare earth SCR catalyst has become a filter.
