| description | To provide a method capable of effectively manufacturing active charcoal large in specific surface area with developed micropore.SOLUTION: A manufacturing method of active charcoal including a process for preparing a chip shaped ash-containing biomass raw material, a raw material cleaning process for inputting the chip shaped biomass raw material into a cleaning water in a treatment tank, conducting boiling and cooling and taking out the chip shaped biomass raw material deposited in the cleaning water, a carbonization process for a carbonization treatment of a cleaned raw material after the raw material cleaning process to obtain carbide, and an activation process for conduction an activation treatment on the carbide to obtain active charcoal. Preferably activation time is set so that specific surface area of the active charcoal is at 1400 m/g or more, more preferably the activation time is set so that specific surface area of the active charcoal is at 2000 m/g or less.SELECTED DRAWING: Figure 7
【課題】ミクロ孔が発達した比表面積の大きな活性炭を効率良く製造できる方法を提供する。【解決手段】本発明に係る活性炭の製造方法は、チップ状の灰分含有バイオマス原料を用意する工程と、チップ状バイオマス原料を処理槽内の洗浄水に投入して煮沸及び冷却を行い、洗浄水内に沈殿したチップ状バイオマス原料を洗浄済原料として取り出す原料洗浄工程と、原料洗浄工程後の洗浄済原料を炭化処理して炭化物を得る炭化工程と、前記炭化物を賦活処理して活性炭を得る賦活工程とを含む。好ましくは、活性炭の比表面積が１４００ｍ２／ｇ以上となるように、賦活時間が設定され、より好ましくは、活性炭の比表面積が２０００ｍ２／ｇ以下となるように、賦活時間が設定される。【選択図】図７ |
