Abstract in another language

A radio frequency cavity perturbation technique is applied in this work to monitor the state of catalysts used in the selective catalytic reduction (SCR) of nitrogen oxides with ammonia. Especially, the NH3 loading on the catalysts is an essential parameter during operation of these exhaust gas aftertreatment systems. In this work it could be shown that the microwave technique is capable to detect the current adsorbed amount of NH₃ in operando on two zeolites with Chabazite framework structure, H-SSZ-13 and Cu exchanged SSZ-13, for different operating conditions.
