Abstract
Disclosed are a slurry for the production of a denitration catalyst, which allows a catalytically active component to be present in the inner region of a ceramic fiber sheet so as to achieve extension of the catalyst life and also allows the production process to be shortened so as to reduce the production cost; a process for producing the slurry; a process for producing a denitration catalyst using the slurry; and a denitration catalyst produced by the process. The slurry of the invention for producing a denitration catalyst comprises a silica sol, titania particles, metavanadic acid particles supported on the titania particles, metatungstic acid particles, and an organic acid ammonium salt.

- 5. A process for producing a slurry for the production of a denitration catalyst, comprising mixing a titania particle powder with a silica sol to form a suspension, adding an ammonium metavanadate powder to the suspension so that the metavanadic acid is supported on the surface of the titania particles, adding ammonium metatungstate to the suspension, and adding an ammonium salt of an organic acid to the suspension.
