Proceedings of the Conference on Biomass Science ( The Japan Institute of Energy ) 13 ( 0 ) 159 - 160 2018.01

Language：Japanese Publishing type：Research paper (conference, symposium, etc.)

<p>Rice straw was treated under hydrothermal condition for producing furfural, which is one of the degradation products of hemicellulose. The highest furfural yield (19.6 mg/g-rice straw) was obtained at 220°C for 15min under hydrothermal condition. Main product was furfural, but the other oxygenated compounds, such as acetic acid and formic acid, were also obtained at this condition. When the phosphoric acid solution was added to the compressed water, the yield of furfural increased remarkably, and the highest yield (26.0 mg/g-rice straw) of the furfural was obtained at 220 °C for 15min. It is shown that addition of phosphoric acid solution to the compressed water provided the higher yield to obtain the furfural from rice straw.</p>

TSUBOTA Toshiki, ISHIMOTO Kotarou, KUMAGAI Satoshi, HATASHI Nobuyuki

Proceedings of the Conference on Biomass Science ( The Japan Institute of Energy ) 12 ( 0 ) 183 - 184 2017.01

Authorship：Lead author Language：Japanese Publishing type：Research paper (conference, symposium, etc.)

<p>In order to use bamboo as the starting material for some high-value products, the production of carbon material, which is activated carbon, for the electrode of electric double layer capacitor (EDLC) was attempted from the bamboo residue after the compressed hot water treatment, which can produce xylo-oligosaccharide from bamboo. The bamboo powder after the treatment of 200 degrees C for 1 hour was used as the starting material of carbon material. The yield from the residue to activated carbon was ca. 10 % regardless of the carbonization temperature. The estimated specific surface areas by BET method for the prepared samples were ca. 2500 m2/g, except for the sample carbonized at 800 degrees C. The capacitance values of the samples were small at high current density. The reason for the small values should be large IR drop.</p>
