Summary
The research objectives are to select the most relevant biomass-derived substrates which can benefit from electrochemical processing, improving the economics of fuel production from biomass sources. Electrochemical processing is being applied to biomass and derived materials to (1) upgrade their energy content, thereby generating fuels and fuel additives (octane or cetane boosters); (2) generate petrochemical substitutes from renewable resources; (3) increase the reactivity and value of the lignin fraction of the wood for a variety of applications of the polymeric materials, therefore generating alternative patterns of utilization of this by-product that can lead to an overall favorable economics of fuel production from biomass sources; and (4) investigate innovative ways of separation of fermentation substrates for subsequent electrochemical processing. We have completed functional group characterization, infrared spectroscopy, /sup 1/H and /sup 13/C nuclear magnetic resonance analyses (90 MHz instrument), and molecular weight distribution of the ethanol-extracted explosively-depressurized aspen lignin (EEEDAL). We have also submitted EEEDAL to electrolysis at constant potential -2.6 V vs Ag/AgCl reference electrode on mercury cathodes in methanol and observed the reduction of carbonyl groups as well as cleavage of side chains in the lignin molecules. The reduced materials have also been characterized. We plan to correlate structure of these well-characterized materials with the properties of the polymers. Replacing phenol with the lignin-derived materials in a thermosetting resin is one possible application.
