“One month DSS Supercritical water gasification test plan for Shochu residue to create renewable energy” (Shochu： Japanese distilled liquor)
Shochu residue is a kind of wet-biomass. Disposal cost is very high, because of its property as easy to rot and heavy. Supercritical water gasification (SCWG) holds promise as a technology to convert shochu residue as wet-biomass into valuable fuel gas treat residue to clear water and provide steam for distillation process of shochu. 60 h Daly start and stop (DSS) SCWG test was succeeded with Radical Scavenger and Rapid heating rate. Therefore, One month DSS test planned for practical use for Distillers’ factory with remodeled pilot plant as NEDO project will report.

“Specification and Quantitation of Fermentation Inhibitor for Hydrothermal Pulverization Pretreatment Using Disk Mill ”
The objective of this research is specification and quantitation of fermentation inhibitor in the liquid sample that was obtained by hydrothermal pulverization pretreatment using disk mill. This pretreatment was conducted using 2.0-2.8 mm particles of eucalyptus for feedstock, and the conditions of gap size between two disks was changed 0.5, 1.0, and 1.5 mm. The liquid samples were analyzed by high performance liquid chromatography and I checked acetic acid and formic acid was detected.
