수증기 부활에 의한제조된 활성탄소섬유의 세공특성

Microporosity of Activated Carbon Fiber Prepared by Steam Activation

김제영, 홍익표

초록

수증기 부활에 의해 핏치계 활성탄소섬유를 제조하였다. 제조된 활성탄소섬유는 Type-I의 등온흡착특성을 나타내었으며 주로 미세기공으로 형성되어 있었다. Burn-off 50%이상인 경우에 비표면적이 1,500M²/g이상의 활성탄소섬유를 제조할 수 있었으며 동일한 burn-off에서는 저온활성화 조건에서 제조한 것이 고온에서 제조한 것보다 높은 비표면적을 가졌다. Horwath-Kawazoe법으로 측정한 결과 활성탄소섬유는 매우 좁은 기공 분포를 가지고 있었으며 burn-off의 증가와 함께 기공의 분포도 넓어지는 경향을 보았다.

Pitch-based activated carbon fibers(ACF) were prepared by steam activation under various conditions. The adsorption isotherm of ACF measured by nitrogen adsorption at 77 K was Type I and ACFs were composed of mainly micropores. The specific surface area of ACF was higher than 1,500㎡/g at burn-off 50%. At the same burn-off %, ACF with higher specific surface area can be prepared under lower activation temperature. The pore size distribution of ACF determined by Horwath-Kawazoe method was very narrow for each samples.
