CATALYST FOR REMOVING NITROGEN OXIDES IN EXHAUST GAS, PRODUCTION THEREOF AND METHOD FOR REMOVING NITROGEN OXIDES IN EXHAUST GAS USING THE CATALYST |
摘要 |
PROBLEM TO BE SOLVED: To efficiently remove NOx within a low temp. region of 150-300 deg.C. SOLUTION: In a method for producing a catalyst removing nitrogen oxides by catalytically reducing nitrogen oxides in exhaust gas by ammonia, titanium oxide containing a sulfate radical is preliminarily baked at 500-700 deg.C or immersed in an alkali soln. to be washed therewith to reduce the content of the sulfate radical to 0.1wt.% or less and this titanium oxide is kneaded and/or impregnated with manganese nitrate and, further, the treated titanium oxide is baked at 200-450 deg.C to support MnO2 on a titanium oxide carrier as an active component to obtain a denitration catalyst. |
