Catalyst of fibrous material for purification of exhaust gases from e.g. vehicles and method of making it

摘要

The invention relates to a catalyst comprising fibres which carry catalytically active material and the invention is characterized in that the fibres have been provided with a porous structure which provides the support for the catalytic material. The invention also comprises a process for the production of the catalyst. It is characterized in that fibres are covered with small particles which are fixed and finally covered with catalytically active material.
