PURPOSE:To manufacture easily a porous carbon body rich in continuous pores and having high strength in simple stages by filling granules of chlorinated vinyl chloride resin into a container after adding a pore increasing agent as required, and calcining the granules by heating in an inert atmosphere. CONSTITUTION:Granules of chlorinated vinyl chloride resin with 500-2,000 polymn. degree are filled into a container. The granules are effectively filled by adding a liq. Which does not dissolve the resin by <=10pts.wt. per 100pts.wt. granules. A pore increasing agent which is vaporized by calcination such as polyolefin powder is preferably added to the granules before filling by <=100pts. wt. per 100pts.wt. granules. The granules in the container are optionally converted into a carbon precursor by heating to 50-300 deg.C in air or an ozone atmosphere, and they are heated to 500 deg.C in an inert atmosphere at 3-100 deg.C/hr heating rate and calcined by heating to >=800 deg.C to obtain a porous carbon body. |
