Slurry for production of denitration catalyst, process for producing the slurry, process for producing denitration catalyst using the slurry and denitration catalyst produced by the process

摘要

Disclosed are a slurry for the produetion 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 produetion process to be shortened so as to reduce the produetion 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.
