发明名称 CATALYTIC FILTER MATERIAL AND METHOD OF MAKING SAME
摘要 <p>The present invention is an improved catalytic filter material for use in removing contaminants such as NOx from a fluid stream . The filter of the present invention employs composite fibers of expanded polytetrafluoroethyle ne (PTFE) filled with catalytic particles. The composite fibers are chopped int o staple fibers and made into a felt material. Preferably, the felt material i s 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 effectivel y catalytically converts undesirable contaminants in the fluid stream to acceptable end products.</p>
