초록

폐각 원료를 수증기 활성화 공정을 거쳐 다공성 흡착제로 제조하여 흡착성능을 평가하였다. 세척.파쇄한 폐각원료를 600 ∼1000 ℃로 탄화시킨 후 700∼800 ℃의 회전로에 주입하는 수증기 활성화법에 의해 활성화공정을 수행하였다. 다양한 조건으로 제조된 폐각흡착제 중 1000 ℃로 탄화시켜 제조된 흡착제가 다른 공정으로 제조된 흡착제에 비해 흡착능이 높게 나타났다. 또한 기상흡착과 액상흡착실험을 통해 흡착제로서의 활용가능성을 확인한 결과 기상흡착의 경우에는 기존 흡착제에 비해 현저히 떨어진 성능을 나타내었으며, 액상흡착의 경우에는 흡착질로 benzene을 선정한 경우 다른 상용 흡착제와 비교하여 거의 유사한 흡착특성을 나타내어 흡착제로서의 활용가능성을 확인할 수 있었다.

The oyster shell adsorbents were prepared by steam activation method to evaluate their adsorption characteristics. Washed and pulverized waste oyster shells were prepared by steam activated process in converter at the temperature range of about 700∼800 ℃ after carbonized at the range of 600∼1000 ℃. The shell carbonized at 1000 ℃ showed the best performance among those of other temperature ranges. Also, comparison between gas and liquid phase adsorption was performed to verify adsorbent possibility of waste shell. In case of gas phase, the adsorbent showed lower performance than existing commercial adsorbents. On the other hand, the liquid phase, they showed similar adsorption performance to commercial adsorbents when benzene was used.
