Research Summary:
Biomass has been seen as one of the viable sources of fuel substitutes. Production of hydrogen from renewable materials is an attractive alternative to production from the now depleting fossil fuels. However, existing technologies such as steam reforming and gasification require high operating temperature and pressures. Aqueous phase reforming, a relatively new method that utilizes much lower temperatures, shows great promise in this field. Simple alcohols and oxygenated compounds such as ethylene glycol, methanol and sorbitol have been used as hydrogen sources for this process. Alkanes may also be produced when more oxygenated starting material like glucose is produced.
The challenge in this research is the production of hydrogen and other possible fuel substitutes directly from biomass. This entails the design and synthesis of functionalized catalysts that can breakdown complex biomass constituents (cellulose, hemicellulose and lignin) into simpler molecules for aqueous phase reforming.
