Journal ArticleDOI
Decomposition of Urea into NH3 for the SCR Process
Sung-Dae Yim,Soo Jean Kim,Joon Hyun Baik,In-Sik Nam,Young Sun Mok,Jong-Hwan Lee,Byong K. Cho,Se H. Oh +7 more
TL;DR: In this article, the thermal and catalytic decomposition of urea over a fixed-bed flow reactor system has been examined for the selective catalytic reduction (SCR) of NOx from mobile sources.
Journal ArticleDOI
Hydrothermal stability of CuSSZ13 for reducing NOx by NH3
TL;DR: In this paper, the authors investigated the deactivation mechanism of the CuSSZ13 catalysts with respect to their Cu/Al ratio and found that the decoupling of deNOx activity due to the aging became more severe as the ratio of the ratio increased.
Journal ArticleDOI
Hydrothermal stability of CuZSM5 catalyst in reducing NO by NH3 for the urea selective catalytic reduction process
Joo-Hyoung Park,Hye Jun Park,Joon Hyun Baik,In-Sik Nam,Chae-Ho Shin,Jong-Hwan Lee,Byong K. Cho,Se H. Oh +7 more
TL;DR: In this article, the performance of the CuZSM5 catalyst in the urea selective catalytic reduction (SCR) process was examined under a simulated feed gas stream containing 10% water at a temperature range of 600-800°C.
Journal ArticleDOI
Mn-Fe/ZSM5 as a low-temperature SCR catalyst to remove NOx from diesel engine exhaust
Young-Jin Kim,Hyuk Jae Kwon,Iljeong Heo,In-Sik Nam,Byong K. Cho,Jin Woo Choung,Moon-Soon Cha,Gwon Koo Yeo +7 more
TL;DR: In this article, a Mn-Fe/ZSM5 catalyst has been developed for removing NOx from diesel engine exhausts and its excellent low-temperature SCR activity and N 2 selectivity demonstrated in comparison with other representative SCR catalysts including CuZSM-5 and a Cu-based commercial catalyst (COM).
Journal ArticleDOI
Control of NOx emissions from diesel engine by selective catalytic reduction (SCR) with urea
TL;DR: In this article, the catalysts screened, including Cu-ion exchanged ZSM5 zeolite, exhibited the highest NO removal activity, particularly at low reaction temperatures below 200 °C, maintaining a wide operating temperature window.
