Abstract:
The reduction of NO by C2H4 in high excess of O2 and temperatures 200−300 °C was investigated using a monolithic electropromoted reactor (MEPR) with twenty-two Rh/YSZ/Pt parallel plate elements. It was found that at 220–240 °C and 10% O2 the selective catalytic reduction (SCR) of NO can be electropromoted by 450% with near 100% selectivity to N2 and ΛNO values up to 2.4. The corresponding rate enhancement ratio of complete C2H4 oxidation is up to 900% with Faradaic efficiency, , values up to 350. The system appears promising for practical applications.
