<P>PROBLEM TO BE SOLVED: To provide a denitrification catalyst manufacturing method by which a denitrification catalyst where vanadium oxide and molybdenum oxide or tungsten oxide are deposited on a titania carrier as active species can simply be manufactured with ease and industrially advantageously without using a solubility improving agent and without necessitating a solvent removing step. <P>SOLUTION: The denitrification catalyst is manufactured by adding the mixed powder of metallic compounds consisting of vanadium oxide powder and molybdenum oxide powder or tungsten oxide powder to a wet cake of hydrous titanium oxide which is a titania precursor to be fired and has a moisture content suitable for kneading, kneading them so that the mixed powder of the metallic compounds is dissolved in the moisture in the wet cake and the metallic compounds are adsorbed on hydrous titanium of the wet cake, and compacting, drying and firing the kneaded material. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
