With increase of the amount of biodiesel production, effective use of the crude glycerol that is the byproduct of bio-diesel production has been social demand. For energy use of crude glycerol, we have investigated gasification of crude glycerol in supercritical water and behavior of potassium which is used in the bio-diesel production, is included in crude glycerol, and can be a cause of reactor plugging. Crude glycerol of 5.0-15.0 wt% was gasified with fine activated carbon catalyst of 1 wt% at 600℃, 25 MPa. Glycerol of 10% concentration was gasified with carbon gasification efficiency of 0.82. Additionally, potassium ion was drained from the reactor by sending water at subcritical temperature.
