초록

활성화제로 KOH, NaOH 및 ZnCl2를 사용하여 폐감귤박으로부터 활성탄을 제조하였다. 최적조건(활성화제의 침적비율 300%, 활성화 온도 : KOH의 경우 900 ℃, NaOH의 경우 700 ℃, ZnCl2의 경우 600 ℃, 활성화 시간 1.5 h)에서 제조한 활성탄을 각각 ACK, ACN 및 ACZ로 명명하였다. 이들 활성탄을 사용하여 회분식 반응기에서 아세톤, 벤젠 및 메틸메르캅탄(MM) 등의 3가지 대상가스에 대한 흡착 특성을 검토하였다. 이들 활성탄에 의한 3가지 대상 가스의 흡착은 Langmuir 모델식보다는 Freundlich 모델식에 더 부합되는 것으로 나타났다. 그리고 흡착 속도실험결과는 유사1차 속도식보다는 유사 2차 속도식에 잘 부합하였으며, 입자 내 확산 모델 결과는 흡착 과정에서 외부물질전달과 입자확산이 동시에 일어나는 것을 시사해 주었다.

Activated carbons were prepared from waste citrus peels using KOH, NaOH, and ZnCl2 as activating chemicals. They were prepared at optimal conditions including the chemical ratio of 300%, activation time of 1.5h, and activation temperature of 900 ℃ for KOH, 700 ℃ for NaOH, and 600 ℃ for ZnCl2, which were named as ACK, ACN, and ACZ, respectively. Using the activated carbons, their adsorption characteristics for three target gases such as acetone, benzene, and methylmercaptan (MM) were carried out in a batch reactor. The adsorption behavior of activated carbons for three target gases followed the Freundlich model better than the Langmuir. And the experimental kinetic data followed a pseudo-second-order kinetic model more than pseudo-first-order one. Following the intraparticle diffusion model suggested that the external mass transfer and particle diffusion were occurred simultaneously during the adsorption process.
