Abstract

A process for production of graphite. The process comprises providing a metallic melt; supplying a carbonaceous material to the metallic melt; subjecting the carbonaceous material to catalytic graphitization in the metallic melt; passing a gas through the metallic melt; and collecting a composition leaving the metallic melt, the composition comprising graphite carried by said gas. An apparatus (100) for production of graphite. The apparatus comprises a graphitization reactor (110); a heating element (120) heating the graphitization reactor; an inlet conduit (130) connecting a source (140) of carbonaceous material with the graphitization reactor; a gas conduit (150) connecting a source (160) of gas with a bottom part of the graphitization reactor; and an outlet conduit (170) connecting a top part of the graphitization reactor with a gas-solids separator (180).
