N2 - A new technology, in which a renewable biomass was used to produce hydrogen fuel, was presented. Degradation and gasification of cellulose-based biomass in compressed water was studied at 100°-400°C. Complete dissolution of the cellulose was achieved at 333°C. The evolution mechanism based on a rapid hydrolysis of the cellulose to oligomers and glucose was suggested. Glucose was then used as a model compound to characterize the chemistry of biomass gasification. Catalytic effects of Pt/Al2O3 on the gasification temperature were determined. A mixture of H2, CO2, and CH4 gas was produced. Quantitative analysis of the total organic carbon in the liquid residue indicated 67% carbon gasification efficiency at 330°C. Qualitative analyses of liquid residues showed that the main decomposition products in the liquid phase were alcohols and carboxylic acids. Thus, the hydrogen fuel could be efficiently generated from biomass. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
