Abstract
The experiments have been made to develop manganese-based sorbent(MT, MFT) for the removal of hydrogen sulfide from simulated hot coal gases. Manganese-based sorbents were tested in an ambient-pressure fixed-bed reactor to calculate H2S removal efficiency. and a three hole jet attrition tester to characterize the sorbent physical properties. According to the experimental results of attrition test. the attrition resistance of 5% bentonite containing sorbent was higher than that of 2% bentonite. The attrition resistances of both sorbents increased with induration temperature. Effects of sulfidation temperature. space velocity. and
모사 고온석탄가스로부터 황화수소를 제거하기 위해 망간계 탈황제(MT, MFT)에 대한 실험을 수행하였다. 망간계 탈황제의 황화수소 제거효율과 탈황제의 물리적 특성을 파악하기 위해 각각 고정층 반응기와 attrition tester를 사용하여 실험하였다. 마멸저항에 대한 실험결과, 벤토나이트를 5% 함유한 탈황제가 2%를 함유한 탈황제보다 마멸저항이 컸으며 또한 경화온도가 높을수록 마멸저항이 큰 것으로 나타났다. 반응온도, 황화수소농도, 그리고 공간속도가 황화수소 제거효율에 미치는 영향을 조사한 결과, MT와 MFT 탈황제 모두
