摘要

Spatially resolved monitoring of the catalytically active state and online catalytic activity measurements were applied to track the fast transient phenomena occurring along the axial direction of a NSR catalyst bed. This methodology clarified the distribution of stored NOx as well as the cause of NOx spike emission.
