Patent ID: 8192712

Claim:
A carbon manufacturing method for producing carbon using cellulose as a starting material, the method comprising the steps of: introducing cellulose and acidic electrolyzed water that has been produced by an electrolytic method, into a sealing reaction vessel; heating a mixture of the cellulose and the acidic electrolyzed water to a predetermined temperature while stirring the mixture; retaining the heated mixture, when it has reached the predetermined temperature, under a saturated vapor pressure for a predetermined period of time while stirring the mixture at the predetermined temperature; cooling the mixture, retained at the saturated vapor pressure for the predetermined period of time, to a room temperature, and obtaining carbon from the mixture, wherein the acidic electrolyzed water has a degree of acidity falling in a range of pH 2.3 to pH 2.7, and the predetermined temperature falls in a range of 230° C. to 250° C.
