Catalyst Production CCRT DOC+CDPF Catalyst Used For Treating
Harmful Tail Gas Of Diesel Buses And Trucks
Product Description
1. The trapping ability of CCRT device is better than that of
nuclear particles.
2. After adopting CCRT device, the engine exhaust backpressure
increases slightly; And the more precious metal loading, the less
increment of pressure drop in CCRT unit, and the better passive
regeneration performance.
3. Although the greater the precious metal loading, the stronger
the CCRT particulate matter trapping ability. However, there will
be a benefit peak when the loading reaches a certain level. After
reaching this peak, although the collection ability can still be
improved by continuously increasing the precious metal loading, the
benefit is not obvious.
