P-111 Characteristics of Hydrothermal Decomposition of Oil Palm Residue Using a Hot-Compressed Water Flow type Equipment

Abstract

Decomposition behavior of each part of oil palm residue (EFB, fiber, trunk, frond) using a hot-compressed water (HCW) flow type reactor at 200℃ was examined. Approximately, 40〜60mg% of the samples was decomposed. Particularly, Most of hemicellulose was solubilized, while most of cellulose remained in the residue. These behaviors did not depend on feed materials. However, in case of lignin, solubilization ratio depended on them. That is, lignin in Trunk and Frond was easy to solubilize in comparison with that in EFB and Fiber.
