| Outline of Final Research Achievements |
In this study, fundamental technology of cascade treatment and fuel production from marine biomass was developed. Production of glucose, which is raw material of bio ethanol, from sea lettuce was investigated by some types of hydrolysis, and dilute sulfuric acid was most effective at 453 K. For the bio oil production from sargassum fulvellum, oil yield was the highest when formic acid aqueous was used as a solvent at 623 K. Gasification and hydrogen production from sargassum fulvellum was studied by high pressure superheated steam and alkali catalyst. At 973 K, gasification rate reached 93% and 1.7 L/g of hydrogen gas was produced from 1g of organic component in sargassum fulvellum.
