Highly-efficient coal utilization technology has greatest concern with the increase in use of fossil fuels. Integrated coal Gasification Combined Cycle (IGCC) is one of promising advanced coal power generation systems. In IGCC, trace elements in the coal tend to be volatilized and subsequently condensed on the ash particles during gas cooling process. Trace elements are removed in the gas cleaning process normally, but fine particles cannot be removed perfectly. These particles cause negative effects such as corrosion. So the method of removing the fine particles is needed. In this study, we propose to make particles with trace element larger via sorbent addition. The objective is estimating the sorbent's adsorption ability for zinc and lead. We confirmed the calcium oxide adsorption ability for zinc in the gasification atmosphere by the adsorption experiments and thermodynamic equilibrium. Calcium oxide absorbs zinc by forming the monoxide structure as a zinc oxide.
