Abstract

Catalyseur complexe destiné à l'épuration des gaz d'échappement dans des installations industrielles et des systèmes à carburant, qui fonctionne dans une gamme de températures entre 300 et 600 °C. Il est constitué d'un corps ayant une surface développée, et il est fabriqué de métaux à effet de valve ou à partir d'alliages Al, Mg, Ti, Zr, Ta. A la surface du corps, on forme par procédé d'oxydation électrolytique au plasma un revêtement de support poreux oxydes / céramique. On applique à ce revêtement de support, par procédé de sédimentation chimique en phase gazeuse, une couche de catalyse active ayant la composition [MxCyOz], dans laquelle Mx est un ou plusieurs métaux de transition des groupes VI-VIII du tableau périodique, de préférence Co, Mn, Cr, x = 99,85-96,00 % en masse, C est carbone, y = 3,00 - 0,10 % en masse, O est oxygène, et z = 1,00-0,50 % en masse.
