Low‐temperature selective catalytic reduction of NO from simulated flue gas by NH 3 on admixtures of iron ore and iron catalyst in a magnetically fluidized bed was experimentally studied. It was found that iron ore exerts a prominent catalytic effect on NO removal resulting in high removal efficiency without magnetic fields. Since iron ore is insensitive to magnetic fields due to its antiferromagnetic property, NO removal efficiency with iron ore as catalyst is only slightly influenced by magnetic fields. The NO removal efficiency, however, can be greatly improved using admixtures of iron ore and iron as catalyst in a magnetically fluidized bed. At defined magnetic field intensity and the same temperature, the removal efficiency reaches higher values compared with that without magnetic fields.
