VANADIUM OXIDE CATALYST IN WHICH TITANIA FOR REMOVING NITROGEN OXIDES IS IMPREGNATED IN COLUMNAR BENTNITE

摘要

PROBLEM TO BE SOLVED: To provide a new catalyst having excellent nitrogen oxide removing activity and capable of increasing the durability to the catalyst poison causing the activity deterioration of the catalyst. SOLUTION: A new catalyst having excellent nitrogen oxide removing activity is manufactured from the titania for removing nitrogen oxides which is immersed in a Ti-PILC manufactured by making titania in column in bentnite by a vanadia catalyst immersed in a columnar bentnite.
