Low-temperature Selective Catalytic Reduction of De-NO_x Based on Iron-based Catalysts

摘要

Low-temperature De-NO_x technology is a new topic in the area of flue gas treatment. This paper presents experimental studies on selective catalytic reduction (SCR) of De-NO_x from flue gas based on iron-based catalysts with ammonia in a fluidized reactor. The iron-based catalysts used in the experiments are particles of Fe_3O_4 and Fe_2O_3. The effects of magnetic fields on SCR of De-NO_x using Fe_2O_3 particles as catalysts are also studied by adding magnetic fields to the fluidized bed. In addition, the iron-based catalysts are analyzed by the X-ray diffraction (XRD) and mossbauer spectrum before and after reaction.
