Abstract
Proton and carbon-13 nuclear magnetic resonance (NMR) spectroscopic analyses were performed on biomass liquefaction products derived from several Canadian and U.S.A. biomass liquefaction processes. This effort was initiated and funded by the Canadian Bioenergy Development Program directed by the Renewable Energy Branch of Energy, Mines and Resources Canada. In general, the carbon-13 NMR data were found more useful than the proton NMR data. Characterization of whole biomass oil samples can be made based on comparison of carbon-13 resonances originating from specific structural units such as methoxyl groups and from specific compounds, for example, acetic and formic acid. Differences between processes for the production of biomass oils can be distinguished based on the relative intensities of different regions such as for alkyl or aromatic resonances. Carbon-13 NMR can also be applied to the investigation of aqueous phases.
