Catalyst for oxidation reaction of metallic mercury and reduction reaction of nitrogen oxides, and exhaust gas purification method

摘要

Titanium dioxide, ammonium molybdate, ammonium metavanadate, phosphoric acid, dihydrate gypsum and water are kneaded in a kneader to obtain a paste, and the paste is applied to a metal lath substrate, followed by drying and firing, to obtain a titanium oxide, an oxide of molybdenum. , An oxide of vanadium, an oxide of phosphorus, and a gypsum to obtain a catalyst for the oxidation reaction of metallic mercury and the reduction of nitrogen oxide.
