In this study we liquefied makgeolli waste by hydrothermal treatment at 310 oC /1h, 1 MPa of N2 initial pressure and an agitation speed of 500 rpm. The liquefied product was then used as a feedstock in the catalytic supercritical water gasification (SCWG) over Ni-Y/Activated charcoal catalyst at 550 oC and 25 MPa. The SCWG experiment was conducted at three feeding rates; 4, 8 and 12 g/min. The total gas production rate was found to be proportional to feeding rate of the liquefied makgeolli waste feed. Gaseous products rich in hydrogen were produced by the SCWG treatments with a maximum hydrogen content of 47.6 mol% which is suitable as a feed for SOFC systems.
