Mo-V-Ti　catalysts　of　low　temperature　denitrification　were　prepared　by　dipping　method.　In　order　to　study　the　activity　of　selective　catalytic　reduction,　the　catalyst　was　placed　in　a　fixed　bed　reactor.　Industrial　flue　gas　was　simulated　with　cylinder　gas.　The　experimental　condition　is　NO:　500ppm,　NH3:500ppm,　O2:8%,　SO2:100ppm,　N2:　equilibrium　gas,　space　velocity:　36000h-1.　Results　indicate　that　the　catalyst　prepared　by　dipping　method　had　good　denitrification　activity　and　sulfur　resistance　at　low　temperature.　The　optimum　ratio　of　catalyst　was　3V2　O5　-6MoO3　-91TiO2　(wt　%).　The　conversion　efficiency　of　NO　was　80~93%,　and　the　conversion　efficiency　of　SO2　was　less　than　1%　at　180~260　°C.　©　2018　Trans　Tech　Publications,　Switzerland.
