Abstract[English]
A washcoat slurry comprising a platinum group metal (PGM) selected from the group consisting of Pt, Pd, Rh and mixtures thereof; an oxygen storage capacity (OSC) material having a D90 in a range of from 1 to 50 µm; an inorganic oxide support; an organic pore former; and a solvent is disclosed. A method for the manufacture of a catalytic gasoline particulate filter for the treatment of an exhaust gas comprises coating a wall-flow filter substrate with the washcoat slurry.[French]
Est divulguée une suspension épaisse pour une couche d'imprégnation comprenant un métal du groupe du platine (PGM) choisi dans le groupe constitué par du Pt, du Pd, du Rh et des mélanges de ceux-ci ; un matériau à capacité de stockage d'oxygène (OSC) présentant un D90 se situant dans une plage allant de 1 à 50 µm ; un support d'oxyde inorganique ; un agent porogène organique ; et un solvant. Un procédé de fabrication d'un filtre à particules d'essence catalytique pour le traitement d'un gaz d'échappement comprend le revêtement d'un substrat de filtre à écoulement sur paroi avec la suspension épaisse pour couche d'imprégnation.
