2795. ----- [ROELEN, O.] [Molding of Mixtures of Solid and Liquid Matter Into Filaments.] German Patent Appl. – filed Sept. 17, 1938; APC 230,512.

Molding a solid-liquid paste, for example, a precipitate suspended in H₂O to form thin filaments or threads; catalyst-carrier systems may be treated in this way. Catalysts for synthetic production of gasoline from CO and H₂ are prepared by precipitation of metal salt solutions. By filtration, the solid residue of such solutions still retains 70-80% H₂O, but can be extruded into thin filaments 1-3 mm. in diameter.
