ABSTRACT:
A hot gas filtration apparatus includes a vessel, a plurality of filter elements mounted within the vessel and positioned such that hot gas flows through said filter elements, with each of said filter elements having a porous body, and a catalytic layer on surfaces of the porous body. The porous body of the filter element may include one of: a porous ceramic monolithic matrix, a continuous fiber reinforced ceramic composite (CFCC) matrix, a metallic matrix, an intermetallic matrix, a superalloy, and a metal-ceramic composite matrix. When the porous body is a nonoxide ceramic, a metallic matrix, an intermetallic matrix, a superalloy, or a metal-ceramic composite matrix, the invention further includes an oxidative resistant layer coating surfaces within the porous body, and the catalytic layer is on the oxidative resistant layer. A porous particulate removal membrane can be positioned on one or more surfaces of the filter element. The porous membrane can also provide a surface for one or more catalysts. The catalysts on the porous surface of the membrane(s) can be the same as or different from the catalysts on surfaces within the porous body.
