ABSTRACT:
A method and an apparatus for producing an active carbon using a carbon-containing material inclusive of an used active carbon as a raw material wherein the carbon-containing raw material is carbonized in a carbonizing unit to produce a carbonized material having electric conductivity and the carbonized material is then activated in an activating treatment unit installed downstream of the carbonizing unit in an atmosphere of steam with a power of electricity induced by electric discharge as well as a function of self-heating of the carbonized material with its own electric resistance are disclosed. The carbonizing unit is constructed in the form of a thermal radiation type batch furnace including an outer wall and a vessel mounted on a firing lattice in the outer wall while a heating chamber is formed therebetween. The activating treatment unit includes a screw conveyor, discharge electrodes arranged in the spaced relationship for inducing electric discharge between adjacent discharge electrodes and a rotary steam pipe having steam spray nozzles attached thereto. Alternatively, the activating treatment unit is constructed in a tunnel furnace including a chain conveyor for conveying the carbonized material, activating chambers, electrode plates on the opposite sides of the chain conveyor, steam spray nozzles, cooling chambers and water spray nozzles.
