Abstract

본 발명은 활성탄과 같이 흡착제로 사용되는 활성탄소섬유의 제조방법에 관한 것으로, 활성탄소섬유의 제조시 탄소섬유를 수산화칼륨(KOH) 용액에 침적시킨 후 적정온도 범위로 열처리하므로서, 활성화 온도가 낮을 뿐만 아니라 수율 및 비 표면적이 우수한 핏치계 활성탄소섬유를 제조하는 방법을 제공하고자 하는데, 그 목적이 있다.The present invention relates to a method for producing activated carbon fibers used as an adsorbent, such as activated carbon. In the manufacture of activated carbon fibers, carbon fibers are immersed in a potassium hydroxide (KOH) solution and heat treated to an appropriate temperature range, thereby lowering the activation temperature. As well as to provide a method for producing a pitch-based activated carbon fiber excellent in yield and specific surface area, an object thereof.

상기한 목적을 달성하기 위한 본 발명은 핏치계 활성탄소섬유의 제조방법에 있어서, 핏치계 범용탄소섬유를 2∼3몰의 농도 범위로 유지되는 수산화 칼륨 용액에 4시간 이상 침적하고 건조시킨 다음, 이를 불활성 분위기에서 10∼25℃/분의 승온속도 및 600∼800℃의 온도범위로 열처리하고 냉각후, 물로 세척 및 건조하는 것을 포함하여 이루어지는 핏치계 활성탄소섬유의 제조방법에 관한 것을 그 요지로 한다.In the present invention for achieving the above object, in the method of producing a pitch-based activated carbon fiber, the pitch-based general carbon fiber is dipped in a potassium hydroxide solution maintained at a concentration range of 2-3 mol and dried for at least 4 hours, and The present invention relates to a method for producing a pitch-based activated carbon fiber comprising heat-treating the same at an elevated temperature rate of 10 to 25 ° C / min and a temperature range of 600 to 800 ° C in an inert atmosphere, followed by cooling, washing and drying with water. do.
