<p><P>PROBLEM TO BE SOLVED: To provide a method for producing activated carbon, by which the activated carbon having the same strength and performance as those of activated carbon produced from coal can stably be produced at a low cost from organic wastes such as waste wood, waste bamboo, waste paper, crushed corn cores or used plastics. <P>SOLUTION: This method for producing the activated carbon, comprising a pre-carbonizing process for pre-carbonizing the organic wastes, a kneading and molding process for kneading and molding the pre-carbonization product obtained in the pre-carbonizing process, and a carbonizing process for carbonizing the molded products obtained in the kneading and molding process, is characterized by mixing and kneading the pre-carbonization product obtained in the pre-carbonizing process with water, mixing and kneading the product with a binder, and then molding the product with a double roll molding machine, in the kneading and molding process. Therein, the binder is preferably added in an amount of 18 to 42 pts.wt. per 100 pts.wt. of the carbonization product, and the water is also preferably added in an amount of 15 to 35 pts.wt. per 100 pts.wt. of the total amount of the carbonization product and the binder added to the carbonization product. <P>COPYRIGHT: (C)2003,JPO</p> |
