Abstract:
The present invention relates to a metal filter for purifying the exhaust gas from a ship, and a preparation method thereof. The purpose of the present invention is to provide: a metal filter for purifying the exhaust gas from a ship, capable of reducing nitrogen oxide by 85% or more at 250-300° C.; and a preparation method thereof. The metal filter for removing nitrogen oxide contained in the exhaust gas from a ship of the present invention comprises an integrated catalyst, wherein a metal substrate comprising irregularities is coated with a low temperature active catalyst in which vanadium (V), tungsten (W) and alumina sol are supported in a Ti-pillared clay (Ti-PILC) powdered support.
