Method of manufacturing deodorizing filter

摘要

A method for manufacturing a honeycomb deodorizing filter including ceramic fibrous paper supporting cuprous oxide or both cuprous oxide and solid acid includes the steps of: soaking ceramic fibrous paper in a slurry; drying the soaked paper; and forming the dried paper into a honeycomb filter. The slurry includes a mixture of a reductant-added water solution with either (i) the cuprous oxide and binder, or (ii) cuprous oxide, solid acid and binder. Alternately, the fibrous paper and binder may first be formed into a honeycomb filter and then soaked in the slurry.
