Abstract：
Polyphenylene sulfide (PPS) filter was treated by nitric acid to form PPSN filter. By the ultrasonic method, PPSN filter was loaded on 40% manganese molar fraction of MnO x-CeO 2 which was calcined at 400°C to form MnO x-CeO 2/PPSN. The activity of MnO x-CeO 2/PPSN was tested in the presence of NH 3 as reducing agent for selective catalytic reduction of NO. The influences of catalyst temperature, volume fraction of NH 3 and O 2, and catalyst loadings on the de-NO efficiency were studied too. It was found that MnO x-CeO 2/PPSN filter with the catalyst loadings of 296 g/m 2showed higher de-NO efficiency under the conditions of temperature 130~160°C, NH 3/NO>1, and O 2 5%. When the catalyst temperature, the volume fraction of NH 3 and O 2 are constant, de-NO efficiency of MnO x-CeO 2/PPSN is higher with the catalyst loading increasing.
