Abstract

PURPOSE:To remove NOx with high efficiency while controlling oxidation of SO2 to SO3 by adding oxide of W, Sn, Mn, Co or Zn to a titanium oxide carrier and then supporting a metal (oxide) for catalytic reduction denitration with NH3. CONSTITUTION:To 1 part by wt. of a titanim oxide carrier is previously added 0.01-1, pref. 0.05-0.2 part of oxide of W, Sn, Mn, Co or Zn. 0.01-1 part of Pt, V2O5, CuO, Fe2O3, WO3, etc. is then supported as an active component on 1 part of te carrier. Exhaust gas contg. NOx and SO2 is brought into contact with the resulting catalyst at above 200 deg.C in the presence of NH3 in an amt. of 0.5-3 times as much as the stoichiometric amt. to the NOx content.
