A biomass-derived carbon material is provided, the carbon material having a carbon content of 60 to 75% by weight and an integrated heat of oxidation reaction of 5 kJ/kg or less when maintained in air at 107° C. for 20 minutes. A method for producing a carbon material is provided, the method including: a carbonization step of obtaining biomass chars having a carbon content of 61 to 75% by weight from biomass; and an oxidation step of heating the biomass chars to 200° C. or higher in an atmosphere having an oxygen concentration of 2 to 13% by volume.

Carbon material and production method therefor

Provided is an oxidation equipment for oxidizing a raw material containing at least one of carbonized coal and a torrefied biomass, the oxidation equipment including: a main body unit forming a fluidized bed; a gas supply unit supplying an oxygen-containing gas so that the raw material flows; a gas discharge unit discharging gas which has passed through the fluidized bed; a cooling unit cooling an oxidized product obtained by oxidizing the raw material; and a delivery unit delivering the oxidized product from the cooling unit, in which the main body unit has a first pressure measurement unit in a freeboard portion and a second pressure measurement unit in a portion through which the fluidized bed passes, and the delivery unit has a delivery amount control unit that controls the delivery amount of the oxidized product based on a differential pressure of the first and second pressure measurement units.
