Particle-fibre-agglomerates

Abstract

Particle fiber agglomerates comprise fibers having the structure of individual fibers, fiber bundles, fiber tufts or mixtures thereof with firmly adhering particles.

We claim:  
     
         1 . Particle-fiber agglomerates, characterized in that these agglomerates comprise fibers having the structure of individual fibers, fiber bundles, fiber tufts or mixtures thereof with firmly adhering particles.  
     
     
         2 . Particle-fiber agglomerates as claimed in  claim 1 , wherein the fibers are glass fibers, ceramic fibers, carbon fibers, graphite fibers, polymer fibers, metal fibers or mixtures thereof.  
     
     
         3 . Particle-fiber agglomerates as claimed in  claim 1  or  2 , wherein the particles comprise inert material, catalytically active material or mixtures thereof.  
     
     
         4 . A process for preparing particle-fiber agglomerates as claimed in any of  claims 1  to  3 , which comprises a) fibers being mixed with a binder and associated with particles or b) fibers and particle powder being mixed in the presence or absence of a binder, pressed to form larger agglomerates and these being broken or hammered to pieces.  
     
     
         5 . The use of particle-fiber agglomerates as claimed in any of  claims 1  to  3  as catalysts.  
     
     
         6 . The use of particle-fiber agglomerates as claimed in any of  claims 1  to  3  as catalysts for mobile applications.  
     
     
         7 . The use of particle-fiber agglomerates as claimed in any of  claims 1  to  3  as catalysts for fuel cells.  
     
     
         8 . The use of particle-fiber agglomerates as claimed in any of  claims 1  to  3  as catalysts for exit gas cleaning.
