Mechanistic Considerations of the NOx Source and the Reducing Agent for Lean NOx Reduction over H-ZSM-5
Journal article, 2009
This study focuses on the reaction mechanism for lean NOx reduction by propane. In particular the role of the NOx-source, i.e. NO or NO2, for the SCR mechanism has been studied by transient experiments using in-situ FTIR spectroscopy and the results are discussed in relation to isopropylamine and ammonia as reducing agents.
