인도네시아 석탄을 이용한 활성탄 제조에 관한 연구
A Study on the Manufacture of Activated Carbon using Indonesian Coal
초록
본 연구에서는 인도네시아산 석탄을 원료로 수증기 활성화 방법으로 Rotary Kiln을 탄화 및 부활로로 이용하여 활성탄을 제조하였으며, 활성화 온도 900℃에서 탄화온도와 반응수증기량이 활성탄의 특성에 미치는 영향을 조사하였다. 최적의 조업조건은 탄화온도 700℃, 활성화온도 900℃에서 총수증기 주입량이 2.7g steam/g char인 경우였으며, 이 조건하에서 제조된 활성탄은 경도 97, 충진밀도 0.48, 요오드흡착력 1,010mg/g, M.B. 흡착력 230mg/g B.E.T. 1,020m2/g의 특성을 나타내었다.
Indonesian coal-based activated carbon was manufactured with steam-reaction method. Also effects of carbonization temperature and steam amount on the process yield and quality of the product were investigated at the activation temperature of 900℃. The rotary kiln type furnace was used for both carbonization and activation and the optimum operation conditions were carbonization temperature of 700℃, steam amount of 2.7g steam/g char and activation temperature of 900℃. At this condition, the iodine value of activated carbon was 1,010 mg/g. Methylene Blue Adsorption Number was 230mg/g and B.E.T. surface area was 1,020m2/g with the hardness about 97.
