CATALYST FOR REMOVING NITROGEN OXIDE AND MANUFACTURING METHOD THEREFOR |
摘要 |
PROBLEM TO BE SOLVED: To obtain a catalyst for removing nitrogen oxides with a low conversion rate to SO3 and excellent durability when ammonia is added to exhaust gas simultaneously containing NOX and SOX and a catalytic reaction is carried out. SOLUTION: The catalyst for removing nitrogen oxides and the manufacturing method therefor are provided. The catalyst contains a composite oxide (A component) obtained using a slurry obtained by neutralizing a mixed aqueous solution of a soluble titanium compound, a soluble silicon compound and/or silica sol or a mixed aqueous solution obtained by further adding a soluble tungsten compound thereto and a slurry obtained by neutralizing a mixed aqueous solution of a meta-titanic acid slurry, a soluble silicon compound and/or silica sol or a mixed aqueous solution obtained by further adding a soluble tungsten compound thereto; and an oxide (component B) of at least one kind of metal selected from the group consisting of vanadium, molybdenum and tungsten. |
