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. Catalyseur constitué de fibres qui contiennent une matière à activité catalytique, ces fibres se caractérisant par le fait qu'elles comportent une structure poreuse qui assure le support de la matière catalytique. Cette invention concerne également un procédé de production du catalyseur qui se caractérise par le fait que les fibres sont d'abord recouvertes de petites particules qui sont fixées, puis recouvertes de la matière à activité catalytique.
