[Challenge] of supply of Paulownia problem, and have not been fully utilized from the performance characteristics, as a fuel, as a water purification material, humidity material, was blessed with excellent effect as a deodorant material, the containers multifunctional paulownia charcoal Establish. A growing 1-3 years of early Narukiri material in 10~100mm of thickness, by selecting the length 300~600mm, and filled into dense vertical combustion furnace box type carbonization furnace provided in the preceding stage And then from the upper part of the carbonization furnace in an inert gas atmosphere, gradually heated, adjust the temperature to a high temperature within a range of less than 500 ℃ than 800 ℃, the Paulownia 5-10 hours Material was allowed to carbonization, a specific surface area of 500~900m 2 / g or more, a specific gravity 0.1~0.3g / cc longer to have Kirisumi 2 a rod-like, multi-functional, which is filled in a container in the granular-like It is Kirisumi 18. .BACKGROUND【課題】桐材の供給の問題、および性能特性から十分に活用されていない、燃料として、浄水材として、調湿材、消臭材として優れた効果を持ち合わせた、容器入り多機能桐炭を確立する。【解決手段】生育1~3年の早成桐材で10~100mmの太さ、長さ300~600mmを選択して、前段に燃焼炉を設けた箱型炭化炉に緻密に縦型に充填して、前記炭化炉の上段部から、不活性ガス雰囲気中で、徐々に昇温して、500℃以上800℃未満の範囲内に高温時に温度を調整して、5~10時間で前記桐材を炭化させて、比表面積500~900m2/g以上、比重0.1~0.3g/ccになっている桐炭2を棒状様、粒状様にして容器に充填されている多機能性桐炭18である。【選択図】図1
