P-13 Reaction mechanism of barley shochu residue in supercritical water

Abstract

The behavior of shochu residue during supercritical water gasification was investigated experimentally. The reaction rates of gasification and char and tar formation were determined. Shochu residue (1.0 wt%) was gasified in supercritical water (SCW) at 600 ℃ and 25 MPa using a tubular reactor. In addition, liquid and solid phase of shochu residue was gasified separately in order to confirm detailed reaction mechanism. The reaction pathway of decomposition of shochu residue was proposed and the reaction rate constants were calculated.
