Document Type and Number:
WIPO Patent Application WO/2024/034620
Kind Code:
A1
Abstract:
Provided is a method for producing a high-strength carbonaceous lump using, as a raw material, a gas containing C in a constituent element. The method for producing a carbonaceous lump according to the present invention has: a carbon precipitation step in which a raw material gas containing a gas containing C in a constituent element is brought into contact with a solid containing Fe in a constituent element to generate a carbon-containing precipitate on a surface of the solid; a step for recovering the carbon-containing precipitate by separating the solid and the carbon-containing precipitate; and then, a lump forming step for obtaining a carbon lump by pressurizing and heating the carbon-containing precipitate.
