Abstract
A fibrous catalytic filter can be used for treating a fluid stream containing particulate matter. The fluid stream is contacted with fibers comprising a catalytic composition. The particulate matter deposits on the fibers and undesirable species within the fluid stream are converted into more desirable species via the catalytic action of the fibers.
Claims27
A purification device, comprising:
- a filter body defining a conduit for fluid flow;
- and
- a porous body of catalytic fibers positioned in the conduit, wherein the catalytic fibers comprise a homogeneous metal oxide catalyst, and wherein the catalytic fibers have a mean diameter of less than 5 microns and a surface area greater than 15 m2/g.
A method for purifying a fluid stream comprising:
- passing a fluid through a porous body of catalytic fibers having a mean diameter of less than 5 microns;
- trapping particulates within the fluid stream in the porous body of catalytic fibers;
- and
- catalyzing the conversion of components within the fluid stream into other species.

A method for fabricating a catalytic filter comprising:
- dissolving metal salts and a polymer in a solvent to form a solution;
- spinning the solution into fibers;
- heating the fibers to produce a catalytic phase;
- and
- supporting the fibers in a housing wherein the fibers can trap particulates from a flowing fluid.
