Impact of sulfur oxide on NH3-SCR over Cu-SAPO-34
Kurnia Wijayanti,Stanislava Andonova,Ashok Kumar,Junhui Li,Krishna Kamasamudram,Neal W. Currier,Aleksey Yezerets,Louise Olsson +7 more
TL;DR: In this article, the impact of sulfur oxide on the activity of Cu-SAPO-34 towards selective catalytic reduction of NOx by NH3 has been conducted to clarify the possible mechanism of deactivation induced by sulfur.
Journal ArticleDOI
A multi-site kinetic model for NH3-SCR over Cu/SSZ-13
Louise Olsson,Kurnia Wijayanti,Kirsten Leistner,Ashok Kumar,Saurabh Y. Joshi,Krishna Kamasamudram,Neal W. Currier,Aleksey Yezerets +7 more
TL;DR: In this article, a kinetic model for ammonia-SCR over a well-characterized Cu/SSZ-13 catalyst was developed to describe the ammonia temperature programmed desorption (TPD) with adsorption at 50 and 150 degrees C as well as ammonia oxidation up to 600 degrees C.
Journal ArticleDOI
Comparison of Cu/BEA, Cu/SSZ-13 and Cu/SAPO-34 for ammonia-SCR reactions
Kirsten Leistner,Oana Mihai,Kurnia Wijayanti,Ashok Kumar,Krishna Kamasamudram,Neal W. Currier,Aleksey Yezerets,Louise Olsson +7 more
TL;DR: In this paper, the effect of small-pore zeolite type on the ammonia-SCR process was investigated using 2.5 wt.% Cu/BEA, 2.6 wt., Cu/SAPO-34 and 3.1 wt, Cu/SSZ-13 catalysts.
Journal ArticleDOI

Journal ArticleDOI
Effect of gas compositions on SO2 poisoning over Cu/SSZ-13 used for NH3-SCR
TL;DR: In this article, the effect of gas composition during SO2 poisoning over Cu/SSZ-13 for NH3-SCR application was performed by conducting SO2-TPD experiments in a variety of lean gas compositions.
