중.소형 폐기물소각로 및 배연탈황공정용 홍합(Hard-Shelled Mussel) 패각폐기물 Sorbent 적용에 관한 연구

Abstract

The objective of this study is to investigate the waste recycling possibility, practicability, economic efficiency and acid gas sorbent use of the hard-shelled mussel. This study is to investigate the hydration/calcination reaction and fixed bed reactor. The physical-chemical characteristics of the hard-shelled mussel were analyzed by ICP, SEM-EDX, BET and pore volume. Thus, the results could be summarized as follows; Hard-shelled mussel can be used as iron-manufacture and chemical sorbents considering more than 53.7% of the mussel is lime content. The SO2 removal efficiency of the hard-shelled mussel after calcined hydration increased thirty times as a result of the higher pore size, specific surface area and pore volume. Also, the CaO content, pore volume, pore size distribution and specific surface area greatly influenced the SO2 and NOx removal reactivity. The optimum particle diameter average of hard-shelled mussel was 100 mesh, which was applied to the sorbent on the medium/small scale waste incinerator and flue gas desulfurization processes.
