Deposition of carbonaceous species over Ag/alumina catalysts for the HC-SCR of NOx under lean conditions: A qualitative and quantitative study
Original language description
The deposition of carbonaceous species on fresh and aged Ag/Al 2O3 catalysts used for the selective catalytic reduction of NOx (HC-SCR) was investigated by a combination of analytical techniques including SEM-EDXA, nitrogen physisorption, GC-MS and TGA.Time-on-stream (TOS) experiments were carried out to determine the level of deactivation over the catalysts. Short-term deactivation was monitored with a MicroGC with a short retention time. In addition, long-term deactivation was also investigated. Hexadecane, a paraffinic component that can be produced by decarboxylation and/or decarbonylation of natural oils and fats, and a standard Finnish commercial diesel fuel were used as the reducing agents. Finally, the influence of hydrogen on the carbonaceousdeposition over the catalyst was also investigated. The NO-to-N2 activity improved in the temperature range 200-500 °C as hexadecane and H2 were used as reducing agents. In the case of commercial diesel fuel, a similar positive effect of
