Title: A LOW ENERGY PROCESS TO PRODUCE A HYDROPHOBIC OIL FROM BIOMASS PYROLYSIS LIQUIDS
Abstract:
Described is a novel process for fractionating biomass pyrolysis oil quantitatively into energy dense hydrophobic aromatic fraction and water-soluble organics in an economical and energy efficient manner. Using the concepts of solvents and anti-solvent behaviours to separate the pyrolysis oil, which is an emulsion, a method utilising minimal quantities of solvents and water is proposed, By comparison with the existing methods to isolate the hydrophobic aromatic fraction, there is a volume reduction of greater than 50:1. Additionally., there is a significant time saving over the 24 hours for the accepted method as a solvent, and the anti-solvent system is spontaneous.
