Abstract

A new technology, in which a renewable biomass is used to produce hydrogen fuel, was presented. This hydrogen could be used as a feed for fuel cells to generate electricity or in other energy-producing processes. 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 was produced. Quantitative analysis of the total organic carbon (TOC) 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. The hydrogen fuel could be efficiently generated from biomass.
