ABSTRACT:
The bran has been less usable and have not been treated as industrial resources. The present invention is a method for producing a porous carbon material product and a hard porous carbon material product which have wide variety of functionalities utilizing such bran which is burned and carbonized stably. The method according to the present invention comprises of the steps of kneading bran with a thermosetting resin and an adequate amount of a solution including an adhesive paste or water, the bran is such as rice bran or wheat bran adjusted grain size; granulating the bran kneaded to predetermined grain size or less; molding the bran granulated in a metal mold by pressurizing and degassing to be a mold; burning and carbonizing the mold detached from the metal mold by heating to desired final burning temperature at a predetermined rate under inactive gas atmosphere or under vacuum; and cooling the mold from the final burning temperature to normal temperature at a predetermined rate.
