Characterization and Fourier Transform Infrared Spectrum Analysis of Bio-oil/Bio-diesel Emulsion

Up to now the direct use of crude bio-oil as transportation fuel has been an impossible goal due to the thermal instability and some other drawbacks of bio-oil. In this paper, we use a simple method to accomplish the goal. Bio-oil and bio-diesel are potential renewable and carbon-neutral alternative to fossil fuel. We mix bio-oil and bio-diesel to get the emulsion using octanol as the emulsifier. The liquids were composed of two layers: bio-diesel rich phase (upper layer) and pyrolytic lignin phase (bottom phase). From the properties, the upper layer seems to be a potential transportation fuel, namely, bio-oil/bio-diesel emulsion. We also study the combustion characteristics and the functional groups information of emulsions.
