Abstract
A method for producing a carbon material including an oxidation step of oxidizing an ashless coal, a forming step of mixing an oxidized ashless coal obtained in the oxidation step and an unoxidized ashless coal and forming a mixture thereof, and a carbonization step of carbonizing a formed body obtained in the formation step. Percentage of increase in oxygen of the oxidized ashless coal obtained in the oxidation step is from 2.0 to 10.0%. A mixing ratio of the oxidized ashless coal in the forming step is from 60 to 95 parts by mass per 100 parts by mass of a total of the oxidized ashless coal and the unoxidized ashless coal.
Claims8
A method for producing a carbon material, the method comprising
- oxidizing an ashless coal to obtain an oxidized ashless coal;
- mixing the oxidized ashless coal and an unoxidized ashless coal and forming a mixture thereof, to obtain a formed body;
- and
- carbonizing the formed body to obtain a carbon material,
- wherein:
- a percentage of increase in oxygen of the oxidized ashless coal obtained in the oxidizing step is from 2.0 to 10.0%;
- and
- the oxidized ashless coal is mixed with the unoxidized ashless coal in an amount of from 60 to 95 parts by mass per 100 parts by mass of a total of the oxidized ashless coal and the unoxidized ashless coal.
