Abstract
A method of using an improved catalytic filter material for removing contaminants such as NO.sub.x from a fluid stream. The filter employs composite fibers of expanded polytetrafluoroethylene (PTFE) filled with catalytic particles. The composite fibers are chopped into staple fibers and made into a felt material. Preferably, the felt material is then laminated on at least one side with a protective microporous membrane. The combined filter removes both macro-particles, such as dust, from the filter stream before the dust can clog active catalytic sites and effectively catalytically coverts undesirable contaminants in the fluid stream to acceptable end products.
