Radio Frequency Studies Of Soot Loading And Ammonia Storage On A Diesel Particulate Filter With A Scr Catalyst Coating, Shreyans Sethia
Dissertations, Master's Theses and Master's Reports
The radio frequency (RF) measurement technique has been shown to be a viable method for measurement of the amount of soot loaded onto DPF’s [1] and the amount of NH3 stored on SCR catalysts [2]. In one of the configurations, a microwave resonant cavity is formed by the metal can encasing the enclosed catalyst. Two metal probes acting as antennas are placed on either side of the catalyst. Power transmitted between the antennas is monitored as the frequency of the signal is swept. At certain frequencies, resonance is achieved. Measurements of the resonance frequencies, amplitude at resonance, and …
An Experimental Investigation Into The Effect Of Particulate Matter On Nox Reduction In A Scr Catalyst On A Dpf, Saksham Gupta
An Experimental Investigation Into The Effect Of Particulate Matter On Nox Reduction In A Scr Catalyst On A Dpf, Saksham Gupta
Dissertations, Master's Theses and Master's Reports
The study of NOx reduction across the SCRF® is presented in this report to understand the inlet and outlet NO, NO2, NH3 species from the SCRF®. The SCRF® is a prototype SCR catalyst on a Diesel Particulate Filter (DPF) that reduces NOx and PM at the downstream location. The SCRF® reduces the packaging volume of the aftertreatment components in order to reduce the cost, volume and weight of the aftertreatment system. A total of 12 experiments were performed on a Cummins ISB 2013 280 hp engine and the aftertreatment system. The …
