<P>PROBLEM TO BE SOLVED: To provide a method for producing activated carbon, by which activated carbon or decomposed products can be directly produced in a short time from organic substances without pretreating them for carbonization; and to provide an apparatus for producing the activated carbon. <P>SOLUTION: The method for producing activated carbon and/or decomposed products comprises charging organic substances into a space where overheated steam and a microwave coexist. In the method, a ceramic heater in a furnace and a sample are irradiated with a microwave, thereby, the temperature of the overheated steam can be controlled precisely, and the temperature distribution in the sample is made small and carbonization proceeds also from the inside of the sample by the irradiation with the microwave, and activated carbon having few closed pores is accordingly obtained, and further decomposed products such as gaseous hydrogen can be obtained at once by utilizing discharge of carbon at a temperature of ≥650°C. The apparatus for producing the activated carbon or decomposed products is also provided. By the method and apparatus, high quality activated carbon and/or decomposed products can be produced at a high efficiency. <P>COPYRIGHT: (C)2008,JPO&INPIT |
