The integrated microwave with Mn/γ-Al2O3 and ozone was employed to oxidize elemental mercury (Hg0) in simulated flue gas. Hg0 oxidation efficiency in the integrated system attained 92.2%. Mn/γ-Al2O3 catalyst was characterized by XRD, XPS, FT-IR, SEM. XPS spectra indicate the formation of a stable mercuric oxide species (HgO) from mercury oxidation. Ozone molecules in air could enhance free radical formation. Hg0 was oxidized to HgO in the presence of ozone and free radical. The coupling role between ozone and radical on mercury oxidation was formed. Microwave catalytic oxidation of elemental mercury reaction with the Mn/γ-Al2O3 catalyst follows Langmuir?Hinshelwood kinetics.
Keywords:Elemental mercury;Mn/γ-Al2O3;Microwave catalytic oxidation;Catalyst characterization and reaction kinetics
