STRUCTURE AND CATALYTIC FILTER FOR FILTERING A GAS COMPRISING A HYDROPHOBIC OR OLEOPHOBIC CEMENT

摘要

The invention concerns an assembled structure useable, after depositing a catalyst, for filtering a gas loaded with soot particles and gaseous pollutants wherein cement is used as coating and/or as joint comprising at least superficially a hydrophobic or oleophobic material. The invention also concerns an assembled catalytic filter obtained after impregnating in a catalytic solution said structure as well as a method for making the filter from said structure.
