This invention is a HfO2-containing catalyst support material for use in high temperature catalytic processes, such as catalytic combustion, wherein the HfO2 is present in a sufficient amount to impart thermal stability on the catalyst support at temperatures in excess of 1,000 ~C, as well as, heterogeneous, supported-platinum group metal catalyst employing the HfO2- containing support material and monolithic catalyst structures in which the HfO2-containing support material is used as a substrate washcoat for the active catalyst material. Also described are high temperature catalytic processes, such as catalytic combustion, employing catalysts and catalyst structures which utilize the HfO2-containing support material.
L'invention porte sur un matériau de support pour catalyseur contenant du HfO¿2? que l'on utilise lors de procédés catalytiques à haute température, tels que la combustion catalytique, la quantité de HfO¿2? étant suffisante pour conférer une stabilité thermique au support de catalyseur à des températures dépassant les 1000 ·C, ainsi que sur un catalyseur hétérogène à métal du groupe du platine sur support recourant au matériau de support contenant du HfO¿2?, et des structures monolithiques de catalyseur dans lesquelles le matériau de support contenant du HfO¿2? s'utilise comme revêtement de lavage de substrat pour le matériau catalytique actif. L'invention porte également sur des procédés catalytiques à haute température, tels que la combustion catalytique, mettant en oeuvre des catalyseurs et des structures de catalyseurs qui ont recours au matériau de support contenant du HfO¿2?.
