基于MnOx-CeO2/PPSN的低温SCR脱硝
Research on de-NO by low-temperature SCR based on MnOx-CeO2/PPSN
摘要
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 MnOI-CeO2 which was calcined at 400 t to form MnOx-CeO2/PPSN. The activity of MnO,-CeO2/PPSN was tested in the presence of NH3 as reducing agent for selective catalytic reduction of NO. The influences of catalyst temperature, volume fraction of NH3 and O2, and catalyst loadings on the de-NO efficiency were studied too. It was found that MnO,-CeO2/PPSN filter with the catalyst loadings of 296 g/m2 showed higher de-NO efficiency under the conditions of temperature 130 ~ 160 t, NH3/NO>1, and O2 5%. When the catalyst temperature, the volume fraction of NH3 and O2 are constant, de-NO efficiency of MnOx-CeO2/PPSN is higher with the catalyst loading increasing.关键词
