Urea-SCR 촉매가 코팅되는 전기히터 시스템의 NOx저감 성능에 관한 연구 = A Study on the NOx Conversion Performance of an Urea-SCR Catalyst coated Electrical Heater System

다국어 초록 (Multilingual Abstract)

It is well known that a urea-SCR system can reduce NOx emissions of a diesel engine effectively. But the urea-SCR technology does not shows a good NOx reduction performance at low temperature exhaust gas conditions. This study introduces a newly developed urea-SCR catalyst coated electrical heater system. This system can reduce NOx emissions of a diesel engine effectively even though at low temperature exhaust gas conditions by increasing the surface temperature of SCR catalyst electrically. The study compares the NOx reduction performance of the newly developed urea-SCR system with a conventional system. This study shows that the new urea-SCR system has high performance and low NH₃ slip at the low temperature exhaust gas conditions.
