1. Reaction Model of Glyceraldehyde Decomposition in Hot Compressed Water 
Glyceraldehyde which is undergo retro aldol condensation had been treated under high temperature (350 450 °C) and high pressure (25 MPa) of water. A reaction network proposed in this study explained relations among decomposition products. Comparison between experimental and model calculation were performed to show characteristics of each reactions. Results indicated that radical reactions predominate in sub and supercritical conditions. 

2.Assesment of Palm Oil Mill Effluent (POME) Gasification in Supercritical Water Gasification for Hydrogen Production 
Nowadays, the expanding of oil palm Industry has given both significant benefit and drawbacks. Besides as a source of national income, production of palm oil obtain a substantial amount of wastes byproducts. One of the most challenging problem is Palm Oil Mill Effluent (POME). In this work, characteristics of Supercritical Water Gasification of POME were investigated in a continous reactor at constant pressure of 25 MPa. The effect of temperature (500-600 °C) and residence time (5-50 s) on gas yield and composition, carbon gasification efficiency (CGE) were studied. The results showed that a higher reaction temperature and a longer residence time could enhance the carbon gasification efficiency of POME and leading to higher hydrogen yield.

 Workshops】≪Biomass Resources
Lecture: Yukihiko MATSUMURA

While depletion of energy resources is regarded as a problem, biomass resources produced by living organisms by using solar energy are attracting attention as renewable energy along with natural energy such as wind power and sunlight. Biomass resources include various types ranging from dry to wet or from waste to produced. In this seminar, we will introduce these biomass resources in the form of workshops.
