패각 폐기물을 이용한 H2S 제거에 관한 연구(I)

열중량분석기를 이용한 황화반응특성

  • 2

In this study, lots of methods have been studing to utilize energy and decrease contaminated effluents. There has been great progress on IGCC (Integrated gasification combined cycle) to reduce thermal energy losses. The following results have been conducted from desulfurization experiments using waste shell to remove H2S. According to TGA results, temperature had influenced on H2S removal efficiency. As desulfurization temperature increased, desulfurization efficiency increased. Also, maximum desulfurization efficiency was observed at 800∘C. Desulfurization was related to calcination temperature. Considering temperature ranges of exhausted gas from hot gas gasification equipment were 400~800∘C. Thus, desulfurization efficiency would be increased desulfurization temperature situation at highly. Experiments by TGA showed that particle size of sorbents had influenced on desulfurization capacity. Maximum desulfurization capacity was observed at 0.631 mm for oyster and clam. Rest of sorbents showed similar capacity within 0.171~0.335 mm particle size range. So, particle size would be considered. When would be used waste shells as IGCC sorbents. According to the results about desulfurization capacity by TGA, oyster had the best desulfurization capacity among limestone and waste shell. We would be identify to substituted oyster for existing sorbents
