Title:
CARBON MATERIAL AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/012773
Kind Code:
A1
Abstract:
Provided is a carbon material which is a biomass-derived carbon material and has a carbon content of 60-75 wt% and which, when held in air at 107°C for 20 minutes, has an integrated quantity of heat generated by oxidation of 5 kJ/kg or less. Also provided is a method for producing the carbon material which comprises a dry distillation step in which carbonized biomass having a carbon content of 61-75 wt% is obtained from biomass and an oxidation step in which the carbonized biomass is heated to 200°C or higher in an atmosphere having an oxygen concentration of 2-13 vol%.
