Graphitization furnace comprising channel comprising plate-shaped wall segments

Abstract

The present disclosure relates to a graphitization furnace (100) configured to graphitize particulate carbonaceous material comprising a raw material inlet (160) and a product outlet (170), and a channel (110) connecting the raw material inlet (160) and the product outlet (170). The channel (110) comprises an upstream section (120) closer to the raw material inlet 160 and a downstream section (130) closer to the product outlet (170). The upstream section (120) has a first cross-sectional area closer to the raw material inlet (160) and a second cross-sectional area closer to the product outlet (170), wherein the second cross-sectional area is larger than the first cross-sectional area. The upstream section (120) and / or the downstream section (130) comprises a plurality of plate- shaped wall segments (140) and the upstream section (120) and / or the downstream section (130) has a polygonal cross-sectional shape.
