摘　　要：以PPS滤料为载体,浸渍Mn-Ce-Ni-Ox粉体悬浮液,经干燥、涂覆PTFE固定化涂层,制备Mn-Ce-Ni-Ox/PPS除尘脱硝双功能滤料。主要研究Mn-Ce-Ni-Ox/PPS滤料的低温脱硝性能。分别探讨Mn-Ce-Ni-Ox负载量、气流速度、水蒸气、SO2等因素对Mn-Ce-Ni-Ox/PPS滤料100-200℃NH3-SCR脱除NO活性的影响。A novel bi-functional Mn-Ce-Ni-Ox/ PPS filter for low-temperature denitrification and dust removal was prepared by impregnation method,using PPS filter as carrier,Mn-Ce-Ni-Oxpowders as catalyst and PTFE foam as immobilized coating. The catalytic performance of Mn-Ce-Ni-Ox/ PPS filter at low temperature was studied. Effects of Mn-Ce-Ni-Oxloadings,flow velocity,water vapor and SO2 on catalytic performance of Mn-Ce-Ni-Ox/ PPS filter for NH3-SCR of NO in temperature range of 100-200 ℃ were separately studied.
