NOVELTY - An activated carbon is formed by thermolyzing waste material (2) in thermal decomposition furnace (1), combusting formed thermolyzed gas (2a) and char (2b) in a melting furnace (7), supplying char collected from furnace (1), dust (2d) from gas (2a) and water vapor (22) to an activation reactor (24) and steam activating the mixture by high temperature waste gas (16), from furnace (7).    USE - For manufacture of activated carbon used in removal of dioxine in waste material such as municipal solid waste.    ADVANTAGE - Activated carbon with high adsorption strength is manufactured economically and efficiently.    DETAILED DESCRIPTION - The waste material is thermolyzed in thermal decomposition furnace. Thermolyzed gas and char formed in the furnace (1) are combusted in a melting furnace and molten slag (11) formed is extracted. Char collected from furnace (1) and dust from thermolyzed gas together with water vapor are guided to an activation reactor as an activated carbon raw material. The mixture in reactor (24) is subjected to steam activation by high temperature waste gas (which acts as heat source) from furnace (7) to form activated carbon (23). An INDEPENDENT CLAIM is also included for an activated carbon manufacturing apparatus comprising dust line (10) of dust collector (6) configured in the middle of thermolysis gas extraction line (5), high temperature waste gas supply line (20) connected to activation reactor and water vapor line (21) from heat recovery boiler (15) (which is installed along the downstream of melting furnace), connected to reactor (24).
