Abstract
In supercritical water gasification, hydrogenation is expected to prevent char formation and to improve gasification efficiency, but hydrogenation reagent has not been specified. Some researchers suspect formic acid, intermediate of water gas shift reaction, is working as a strong hydrogenation reagent. In this study, experimental work was conducted to find the characteristics of formic acid and 2-propanol production in supercritical water gasification of glucose, where the former should be produced by partial oxidation, and the latter is produced from acetone, intentionally added to detect hydrogenation.
