  • Process for manufacturing a catalyst body for generating hydrogen and a catalyst body for generating hydrogen
    Patent number: 6432871
    Abstract: A process for manufacturing a catalyst body for generating hydrogen having at least one thin, large-surface catalyst layer, through which the reaction mixture can be passed includes steps of pressing a copper powder (particularly dendritic copper) to form a thin and highly compressed layer which forms a formed body, sintering, the formed body in a reducing atmosphere so that a net-type carrier structure made of copper is formed, and activating a surface layer of the formed body.

  • Process for manufacturing a catalytic material
    Patent number: 6197365
    Abstract: A method for manufacturing a catalytic converter includes spraying a suspension comprising a solvent and a catalyst material comprising carrier particles coated with a catalytically active material onto a substrate having a temperature above the boiling point of the solvent via a sprayer; and forming a layer on the substrate. The layer is thermally activated and is wetted three-dimensionally.
