COMPOSITIONAL ANALYSIS OF BIO-OIL AND EMULSIFICATION OF BIO-OIL IN DIESEL FUEL
The complicated bio-oil pyrolysed from biomass in a fluid bed reactor was comprised of two fractions: water-soluble and water-insoluble fractions. The water-soluble fraction extracted by dichloromethane (CH2Cl2,) was analyzed using gas chromatography/mass spectrometry (GC/MS). Except acetic acid and 2-Propanone, 1-hydroxy, the major chemical compositions identified, several kinds of compounds matched well with the database were also detected and some of them could not be detected before extraction. Therefore, the method of extraction with CH2Cl2 is feasible. Water-insoluble fraction analyzed by GC/MS was more complicated and the detection method need be studied further. The emulsion fuels were made by three proportion, including bio-oil, diesel fuel, and emulsifier which was a mixture of Span-80 and Tween-20 at a certain ratio. Experiments were done to study the stabilization of emulsions fuels, and it was concluded that short residence time, higher concentration of bio-oil and lower concentration of emulsifier could lead to poor stability. Three kinds of physical characteristics of emulsions products were studied and the results shown that with the increasing of concentration of bio-oil, the heat value and pH were decrease, while viscosity increased. And the heat value would be increased gradually with the increasing of restore time.
