  • Patent number: 4019969
    Abstract: This invention relates to a method of manufacturing catalytic tubes with wall-supported catalyst particularly for steam reforming of hydrocarbons and methanation, wherein at first a porous layer of metal sponge is laid on the tube surface by the known method of electrolysis, wherein said tube is permanently filled with electrolyte and a shield mounted on the anode is raised step by step or in continuous manner during electrolysis. Said tube constitutes a cathode during electrolysis, and a metal bar placed in the axis of the tube forms an anode. The tube is roasted at a temperature of 800.degree.-1200.degree. C, then salts are introduced into the sponge, which after roasting yield metal oxides irreducible in the presence of a hydrogen and salts, which yield reducible metal oxides, and coating the layer with salts is performed by known methods using aqueous solutions of salts, and after coating the roasting is carried out.
