초록
고온 연료가스 정제를 위하여 ZnO-CuO 혼합탈황제를 제조하였으며, 탈황제들의 반응특성을 조사하였다. ZnO와 CuO의 혼합비율에 따른 황화반응 속도는 CuO의 함량이 증가할수록 빨라졌다. ZnO와 CuO 비율을 달리한 각 탈황제의 재생특성을 조사하기 위하여 TPO실험을 수행한 결과,
ZnO-CuO mixed sorbents for desulfurization in hot gas cleaning process Were prepared and investigation on their characteristics was performed in this study. The rate of sulfidation increased as the amount of copper oxide in the composite sorbent was raised. TPO experiments were carried out to investigate the characteristics of the regeneration of the sorbents with severa1 different ratios of Zno to CuO. Copper sulfate was formed at temperatures above
