CATALYTIC FILTER FOR FILTERING A GAS COMPRISING A COATING AND/OR A JOINT WITH CONTROLLED POROSITY

摘要

The invention concerns a catalytic filter for depolluting a gas loaded with soot particles and gaseous pollutants, obtained by impregnating in a catalytic solution a filtering structure formed by an assembly of honeycomb-type monolithic elements, wherein the porosity of the cement used as coating and/or as joint and/or as plug is less than the porosity of the material constituting said element(s).
