N2O Decomposition over Fe-ZSM-5: A Systematic Study in the Generation of Active Sites

Lioubov Kiwi, Fernando Cardenas Lizana, Bryan Bromley

We have carried out a systematic investigation of the critical activation parameters (i.e., final temperature (673-1273 K), atmosphere (He vs. O-2/He), and final isothermal hold (1 min-15 h) on the generation of "alpha-sites", responsible for the direct N2 ...

Nitrous Oxide Abatement over Fe-Zeolite

Bryan Bromley

The use of zeolites for catalytic reactions is a field in continuous development. Since it was demonstrated that metal-zeolites are efficient catalysts for NOx abatement, decomposition of nitrous oxide (N2O) over Fe-containing zeolites has attracted great ...

Do synthetic Fe-zeolites mimic biological Fe-porphyrins in reactions with nitric oxide?

Lioubov Kiwi, Bryan Bromley

Iron containing ZSM-5 zeolites is extremely active in nitrous oxide decomposition. This reaction involves atomic oxygen species known as "alpha oxygen" on iron sites. Despite the multiple techniques devoted to its characterization, the active sites' struct ...

Theoretical evidence of the observed kinetic order dependence on temperature during the N2O decomposition over Fe-ZSM-5

Lioubov Kiwi, Bryan Bromley

The characterization of Fe/ZSM5 zeolite materials, the nature of Fe-sites active in N2O direct decomposition, as well as the rate limiting step are still a matter of debate. The mechanism of N2O decomposition on the binuclear oxo-hydroxo bridged extraframe ...

Structured catalytic wall microreactor for efficient performance of exothermic reactions

Lioubov Kiwi, Bryan Bromley, Marina Ruta, Turan Eslanloo Pereira

A novel microreactor with structured catalytic wall (SCWMR) has been developed for highly exothermic, gas/solid reactions and tested for the selective acetylene hydrogenation. The reactor design is similar to the so-called "slit microreactor". The structur ...

N2O Decomposition over Fe-ZSM-5 Studied by Transient Techniques

Albert Renken, Lioubov Kiwi, Bryan Bromley, Petra Prechtl

N2O decomposition to gaseous N-2 and O-2 catalyzed by a commercial Fe-ZSM-5 has been studied by different transient techniques: (i) via the transient response methods at ambient pressure, (ii) via the temporal analysis of products (TAP) reactor under vacuu ...

“Sandwich Reactor” for Heterogeneous Catalytic Processes: N2O Decomposition as a Case Study

Albert Renken, Lioubov Kiwi, Bryan Bromley

A novel “sandwich” microreactor designed as a thin (∼ 300
