| Abstract: | The process principle, process and technical characteristics of ultra-low temperature liquid-phase catalytic reduction denitrification process are introduced. The NO in flue gas is catalysed to form free radical Nx·Ox, which is catalysed to generate N2 and H2O under the action of reducing agent. The denitrification should be carried out at ultra-low temperature, and the denitrification efficiency can reach over 95% at 40-130℃, exhaust gas ρ(NOx) < 50 mg/m3. |
