  • Smokeless porous carbon production method and its production system
    Patent number: 7354557
    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.
