Model studies of sulfur deactivation of NOx storage catalysts
Journal article, 2004
Model NOx storage catalysts were used to study the sulfur deactivation of these systems using reactor studies, FTIR and XPS. It is found that the deactivation rate shows a linear dependence on the SO2 concentration and that bulk sulfates are easily formed. Experiments with SO2 present either during lean or during rich conditions show a more rapid deactivation in the latter case.
