Hydrothermal carbonization reaction converts biomass to the value added product such as hydrochar. During the reaction, bio-oil has been also produced by hydrothermal carbonization reaction (HTC) as a byproduct. Even though its yield cannot be ignored in number, the research on bio-oil generated from HTC reaction of biomass has not been actively conducted. Especially, the composition of feedstock which is not homogeneous may make the characterization of bio-oil different from bio-oil generated from the different reaction. In this study, bio-oil from the hydrothermal carbonization reaction of food wastes has been produced. To characterize the bio-oil, two different methods have been applied; column chromatography and liquid-liquid extraction. Different elution with various solvents may categorize the various components. Various solvents have been prepared for various polarity. The eluents and fractions obtained from two different methods have been analyzed by gas chromatography (Agilent 7820) and a mass spectrometer (MSD, Agilent 5977) with a capillary column (HP-5, 30 m � 0.20 mm � 0.33 �m). The more detailed compounds identified in bio-oil will be presented in this poster.
