Patent ID: 8388898

Claim:
A ceramic filter element for hot-gas filtration, comprising: a first layer in the flow direction for particle separation and a second layer providing a support body, wherein the support body comprises support material particles selected from the group consisting of SiC, mullite, and aluminum oxide, bonding material, and catalyst material, the catalyst material being selected from the group consisting of one or more oxides of rare earth metals, one or more aluminates, titanates, and TiO 2 , and the catalyst material being doped with a promoter, the promoter being selected from the group consisting of platinum, palladium, rhodium, gold, silver, nickel, copper, manganese and cobalt, wherein the support body, including the support material particles, the bonding material, and the catalyst material, is a sintered support body, and the support material particles are bonded to one another at least partly by the catalyst material, and the catalyst and bonding materials are present as composite particles comprising 90-99% by weight catalyst material and a remainder of bonding material.
