2004-03-06 · The selective catalytic reduction (SCR) of N2O with CH4 in the absence and presence of excess O2 has been studied over ion-exchanged Fe−BEA catalyst by the combination of an activity test with in-situ infrared spectroscopy to understand the nature of the surface species involved in the SCR of N2O with CH4. From the results of flow reaction

Though accurate at the time of publication, it is no longer being updated. The uncertainty ranges in calculated N2O and CH4 global lifetimes computed using the SPARC estimated uncertainties are reduced by nearly a factor of two compared with uncertainties from Sander et al.. Uncertainties in CH4 loss due to reaction with OH and O (1D) have relatively small impacts on present day global total ozone (±0.2-0.3%). The reaction mechanisms of selective catalytic reduction (SCR) of N 2O with CH4 and N2O decomposition over Fe ion-exchanged zeolite catalysts (Fe-BEA, Fe … 2004-01-01 Uncertainty in the Cl + CH4 reaction affects the amount of chlorine in radical vs. reservoir forms and has a modest impact on present day SH polar ozone (~±6%), and on the rate of past ozone N2O removal by catalytic decomposition and reduction with CH4 over Fe/Al2O3 was investigated.

As a product of radiolysis and chemical reactions, nitrous oxide was observed in nuclear waste storage facilities, together with hydrogen, methane and 1 Introduction. Methane (CH 4) and nitrous oxide (N 2 O) are key atmospheric trace gases that impact stratospheric ozone abundances and radiative forcing of the atmosphere. N 2 O is a long‐lived (well‐mixed) atmospheric trace species with an estimated steady state lifetime of 123 years [Stratospheric Processes and their Role in Climate (SPARC), 2013]. To assess the reaction kinetics reactions were conducted within a temperature range of 300 °C–550 °C and at atmospheric pressure, and the composition of reactant feed (N2O/CH4) was varied between three fixed ratios (5, 3, and 1). TPD, XRD, TEM and FT-IR techniques were used for catalyst characterization and mechanistic studies.
