    摘要: Provided is a preparation method of a denitration catalyst for treating nitrogen oxides contained in exhaust gas discharged from gas turbines for generating plants, coil fired boilers, etc., in which the catalytic activity can be improved, and furthermore, an increase of the cost of producing the catalyst is not involved. The preparation method of a denitration catalyst used when reacting nitrogen oxides with reducing agent ammonia to decompose the nitrogen oxides into nitrogen and water, and including titanium oxide and vanadium as catalytic active ingredients thereof, is characterized in that the vanadium precursor is ammonium metavanadate powder, the ammonium metavanadate powder containing particles having a particle diameter of 10 μm or less in a cumulative ratio of 20% or more. The ammonium metavanadate powder is preferably a reclaimed product including vanadium recovered from petroleum-based combustion ash such as heavy oil ash.
