Abstract
Possibility of hydrogen generation from the organic materials using SCW was demonstrated. Higher yield of hydrogen generation was confirmed for higher polyhydric alcohols, such as glycerin and ethylenglycol, where the higher gasification rate was a dominant factor for the generation. The results obtained of the yields of hydrogen generation were still small for the practical utilization; however, several important factors for the decomposition were obtained. Thermodynamic consideration was also carried out.
