PURPOSE: A preparation method of porous carbon materials using charcoal instead of graphite which is conventional raw material, is provided, which reduces the production cost and give high efficiency carbon products used in bioengineering, health and construction fields. CONSTITUTION: The method comprises the steps of: drying ground charcoal as a raw material; mixing charcoal with a suitable ratio according to a different size for a use; adding an aging solution made of 70% of methyl alcohol and 30% of sap of black oak, to be a ratio charcoal/aging solution of 70-85% : 15-30%; aging at 70-80deg.C for 2-8hrs.; heating to 100-200deg.C and molding under 10-50kg/cm¬2 of pressure; demolding; carbonizing at 450deg.C for 4-10hrs. and then at 800-1300deg.C for 8-32hrs to form a high strength carbonized structure.
