A pliable refractory metal carrier () may have coated thereon an anchor layer () to improve adherence to the carrier () of a catalytic coating (). The conformable catalyst member () may be bent to conform to a curved or bent exhaust pipe () within which it is mounted. The pliable metal carrier may be in the form of a tube such as carrier () having perforations () formed therein, or it may be a metal strip () which is folded into accordion pleats () and has perforations () formed therein. The perforations () serve to permit the passage of exhaust gas therethrough. A series of interior closures () and annular baffles () may be provided to import a serpentine flow path to gases flowed through an exhaust pipe () containing a conformable catalyst member () therein. A mounting member () may be supplied to fasten one end of the conformable catalyst member () to the discharge end of an exhaust pipe ().

Metal catalyst carriers and catalyst members made therefrom

A method for treating cooking fumes to oxidize oxidizeable particulate and gaseous components thereof includes contacting the fumes with a catalytic material containing ceria and alumina each having a BET surface of at least about 10 m.sup.2 /g, for example, ceria and activated alumina in a weight ratio of from about 1.5:1 and 1:1.5 and a BET surface area of from about 25 m.sup.2 /g to 200 m.sup.2 /g. Optionally, a catalytic metal component such as platinum or palladium may be included in the catalytic material. The foodstuffs cooking fumes are contacted with the catalyst composition (22 or 40) at a temperature of 200.degree. C. to 600.degree. C. to promote the oxidation of both particulate (atomized) animal and/or vegetable oils and fats and oxidizeable gas phase components of the fumes. Optionally, a separate, supplemental gas phase oxidation catalyst (42) may be used in conjunction with and downstream of the above-described catalyst (40) to provide a two-catalyst system for treating cooking fumes.

A combustor for supporting the catalytic combustion of gaseous carbonaceous fuel contains a catalyst zone in which is disposed a catalyst body comprising at least one catalyst member, a separator zone comprising a separator body and a downstream zone where homogeneous combustion occurs. The catalyst member contains a carrier and a catalyst material deposited thereon. The catalyst body may, optionally, contain additional catalyst members downstream of the at least one catalyst member. The separator body contains a carrier-type monolith containing ceramic fibers in a matrix. One of the optional additional catalyst members may also contain such a monolith on which the catalyst composition is disposed.

Particles of an interconnected three-dimensional network of bar-like topaz crystals are used as a reactant (with added silicon dioxide, or a mixture with added silicon dioxide and hydrated aluminum fluoride or added silicon dioxide, hydrated aluminum fluoride and alumina) to form mullite whisker honeycomb articles suitable as catalyst supports.
