Abstract

Two different thermo-chemical conversion processes were used to convert waste lipid, soapstock, into bio-oils. In the first one, dried soapstock was converted into pyrolysis bio-oils through pyrolysis process at 450°C under nitrogen atmosphere. The other process, hydrothermal liquefaction produced two hydrothermal liquefaction bio-oils from high moisture soapstock (20 and 50% solids) at 300°C. These three bio-oils were analyzed for their physical properties, such as viscosity, density, elemental analysis, heating value, boiling point and molecular weight distribution. Structural characterization was carried out using advanced spectroscopic and chromatographic techniques, such as NMR, FTIR, TLC-FID, and GC-MS to provide insight on carbon and hydrogen distribution, functional groups, hydrocarbon class type distribution, and main components present in it. The results were used to explain the influence of each process on bio-oil yield, composition and structures present in it.
