摘要

One technological process employing ozone and heterogeneous catalyst-sorbents was proposed for removal of SO2 from flue gas. The catalyst-sorbents were developed and tested especially for adsorption and oxidation of SO2. Alternative catalyst-supporters including γ-Al2O3, permutite, silica gel, activated carbon and diatomite combined with different metal oxides (MnO2, Cr2O3, Fe2O3, CuO, CoO and NiO) were evaluated and tested. It was found that γ-Al2O3 doped with MnO2 can be considered as removal-effective sorbent for adsorption and oxidation of SO2. The synergetic effect between ozone and catalyst was found to be dominated. Effects of catalyst preparation parameters like calcination temperature, metal loaded and reaction temperature, etc. were investigated based on the MnO2/Al2O3 catalyst-sorbents. Results show that γ-Al2O3 combined with 8% Mn, calcinated under 573 K and reacted at 413 K are the optimal parameters for removal of SO2. Extra NO in flue gas can slightly enhance the capture efficiency of SO2.View full textDownload full textKeywordsOzone, SO2 , NOx , Catalyst-sorbents, Flue gas treatmentRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/01919512.2012.663726
