66.液化残渣の二次イオン質量分析によるキャラクタリゼーション

抄録

In order to examine the feasibility of catalyst recovery from liquefaction residue, fundamental study on the properties of catalyst in the residue was carried out by using two and three dimensional SIMS imaging techniques. Residues were obtained from 1t/d NEDOL PSU plant which uses Illinois coal as feedstock and synthetic pyrite as catalyst. The results suggested that the SIMS imaging provides a promising technique for the examination of liquefaction residue. However, interpretation becomes complicated when molecular secondary ion is present.
