ABSTRACT:
A filtering catalytic substrate including a non-woven fibrous refractory body, a plurality of channels formed in the body, a washcoat layer at least partially coating the channels, and a catalyst material at least partially coating the washcoat. The body is substantially composed of interlocking fibers fabricated using methods of forming a rigid matrix of ceramic fibers to provide a porous substrate for filtration applications.
