Direct coal injection to a gas turbine is expected as an advanced high efficiency power generation technology. "Hyper-Coal" is a fuel to the direct coal injection, and must be extremely low ash and low alkaline and alkaline-earth metals concentration. In this paper, in order to incorporate "alkaline and alkaline-earth metals removal process" into "coal solvent extraction process", the ion exchange treatment with H-Y zeolite were investigated under high temperature and pressure condition (360℃, 10atm). Agglomeration test of the zeolite and Removal Test of Dissolving Sodium in Nonpolar Solvent were also examined.
