Title: NH₃-SCR on Cu, Fe and Cu + Fe exchanged beta and SSZ-13 catalysts: Hydrothermal aging and propylene poisoning effects

Abstract

Cu, Fe and Cu + Fe ion exchanged Beta and SSZ-13 catalysts were prepared by solution ion exchange using commercial NH₄/Beta, and NH₄/SSZ-13 that was prepared in-house. To study hydrothermal aging effects, Beta supported catalysts were aged hydrothermally at 700 °C and SSZ-13 supported catalysts were aged at 750 °C. In order to reveal the effects of Fe addition in the co-exchanged catalysts, these catalysts were characterized by means of powder X-ray diffraction (XRD), N₂ adsorption-desorption, electron paramagnetic resonance (EPR), ²⁷Al-nuclear magnetic resonance (²⁷Al-NMR) and propylene coking followed with temperature programmed reaction (TPR), and further tested with standard NH₃-SCR with and without the presence of propylene. Collectively, the catalyst characterizations and reaction testing indicated minor beneficial effects of Fe addition in Cu,Fe/Beta, where NH₃-SCR activity, N₂ selectivity and hydrothermal stability were all slightly improved. In contrast, Fe addition did not show apparent beneficial effects in low-temperature SCR for the Cu,Fe/SSZ-13 case. In conclusion, at elevated reaction temperatures, however, the presence of Fe indeed considerably improved NO conversion and N₂ selectivity for the hydrothermally aged Cu,Fe/SSZ-13 catalyst in the presence of propylene.

NH3-SCR on Cu, Fe and Cu+Fe exchanged Beta and SSZ-13 catalysts: hydrothermal aging and propylene poisoning effects

Journal Article Wang, Aiyong ; Wang, Yilin ; Walter, Eric D. ; ... - Catalysis Today

Cu, Fe and Cu+Fe ion exchanged Beta and SSZ-13 catalysts were prepared by solution ion exchange using commercial NH4/Beta, and NH4/SSZ-13 that was prepared in-house. To study hydrothermal aging effects, Beta supported catalysts were aged hydrothermally at 700 C and SSZ-13 supported catalysts were aged at 750 C. In order to reveal the effects of Fe addition in the co-exchanged catalysts, these catalysts were characterized by means of powder X-ray diffraction (XRD), N2 adsorption-desorption, electron paramagnetic resonance (EPR), 27Al-nuclear magnetic resonance (27Al-NMR) and propylene coking followed with temperature programmed reaction (TPR), and further tested with standard NH3-SCR with and withoutmore »« less

Influences of Na⁺ co-cation on the structure and performance of Cu/SSZ-13 selective catalytic reduction catalysts

Journal Article Cui, Yanran ; Wang, Yilin ; Walter, Eric D. ; ... - Catalysis Today

Here, a series of Cu,H/SSZ-13 and Cu,Na/SSZ-13 catalysts were synthesized, degreened and hydrothermally aged for use in the standard NH₃-SCR reaction. Surface area/pore volume and XRD analyses were used to probe the textural properties of the catalysts. H₂-TPR and EPR were utilized to quantitatively describe the various Cu species. NH₃-SCR was tested at both a lower space velocity to probe the light-off behavior, and at a higher space velocity to generate data for kinetic analysis. Na⁺ co-cation addition was found to promote turnover rates of isolated Cu-ions at low reaction temperatures. However, this promoting effect is compromised by decreases inmore »« less

A Comparative Kinetics Study between Cu/SSZ-13 and Fe/SSZ-13 SCR Catalysts

Journal Article Gao, Feng ; Wang, Yilin ; Kollar, Marton ; ... - Catalysis Today

Cu- and Fe/SSZ-13 catalysts with the same Cu(Fe)/Al ratios are synthesized using the same parent SSZ-13 starting material. The catalytic performance for both fresh and hydrothermally aged catalysts is tested with NO and NH3 oxidation, and standard SCR reactions under steady-state conditions, and standard and fast SCR under temperature-programmed conditions. For standard SCR, Cu/SSZ-13 shows much better low-temperature performance which can be explained by NH3-inhibition of Fe/SSZ-13. During hydrothermal aging, both catalysts undergo dealumination but Fe/SSZ-13 dealuminates more severely. For aged catalysts, Cu/SSZ-13 gains oxidation activities due to formation of CuOx. However, Fe/SSZ-13 loses oxidation activities although formation of FeOxmore »« less

A redox model for NO oxidation, NH₃ oxidation and high temperature standard SCR over Cu-SSZ-13

Journal Article Daya, Rohil ; Deka, Dhruba J. ; Goswami, Anshuman ; ... - Applied Catalysis. B, Environmental

A kinetic model is developed to predict the influence of temperature and hydrothermal aging on the redox of active Cu sites under standard SCR, NO oxidation and NH₃ oxidation conditions over a practically relevant fully-formulated Cu-SSZ-13 catalyst. NO₂/N₂ production during NO/NH₃ titration of Cu^II sites is utilized to identify rate parameters associated with NO-only RHC (reduction half cycle) and NH₃-only RHC respectively. Integral N₂ formation during subsequent NO + NH₃ titration is consistent with the production of one NO₂ per two CuII sites reduced during NO-only RHC and one N₂ per six Cu^II sites reduced during NH₃-only RHC. Decreased reductionmore »« less

Hydrothermal Aging Effects on Fe/SSZ-13 and Fe/Beta NH3–SCR Catalysts

Journal Article Gao, Feng ; Szanyi, János ; Wang, Yilin ; ... - Topics in Catalysis

Cu/SSZ-13 has been successfully commercialized as a diesel engine exhaust aftertreatment SCR catalyst in the past few years. This catalyst, however, displays undesirable NH3-SCR selectivity at elevated reaction temperature (≥ 350 C) after hydrothermal aging. Fe/zeolites, despite the fact that most of them degrade beyond tolerance after hydrothermal aging at temperatures ≥ 650 C, typically maintain good SCR selectivities. In recent years, Fe/beta has been identified as one of the more robust Fe/zeolites for use in NH3-SCR, where activity maintains even after hydrothermal aging at 750 C. Very recently, we, for the first time, synthesized and tested NH3-SCR performance formore »« less
