The Comparison of Selective Catalytic Reduction of De-NOx on Iron -Based Materials

Elementary studies of different catalysts on the fluidized bed are done based on iron and iron oxides in selective catalytic reduction (SCR). Under different temperatures and catalysts, there are distinct conversions. This paper compares the conversion of FeN Fe₂O₃ and Fe₃O₄ within a certain temperature range. The result indicated that the iron oxide has some activation of De-NOx , in particular the maghemite, the conversion of NO_x on the pure maghemite reaches 91% at 250 degC.
