ABSTRACT:
A smokeless porous carbon production method and its production system in which porous carbon is produced by heat treating a large amount of material, e.g. wood or bamboo, efficiently in a short time with thermal energy generated by combusting combustible gas produced by heating the material, without combusting the material completely by regulating inflow of air. The smokeless porous carbon production system comprises a sequential carbonization chamber (12) for heating a material M, e.g. wood or bamboo, charged in from a material charging opening from below to carbonize the material sequentially and to generate combustible gas, a high heat treatment chamber (13) disposed below the sequential carbonization chamber continuously thereto, a residual gas combustion chamber (16) communicating with the high heat treatment chamber through a lower opening, an exhaust pipe (17) disposed continuously to the residual gas combustion chamber while being directed upward, and means for taking out an intermediate carbide subjected to high heat treatment in the high heat treatment chamber to the outside of a furnace, wherein air regulation openings (15) for taking in an appropriate amount of outer air are provided in the outer walls of the high heat treatment chamber and the residual gas combustion chamber.
