Bio-oil is a complex mixture of polar and non-polar compounds, and cannot be used directly as a combustion engine fuel due to its low heating value, high viscosity, chemical instability and incomplete volatility. In an attempt to produce liquid engine fuel from the bio-oil, solvent extraction and fractionation of bio-oil was studied and optimized. Fractions obtained were then characterized using GC/MS, FTIR and thermogravimetric techniques (TG). The lighter oily components (light oil) extracted from the raw bio-oil was evaluated for its miscibility with gasoline and the carbon residue in air after combustion. The suitability of the light oil as an engine fuel was discussed.
