Appling a thermochemical liquefaction process to convert marine microalgae，Dunaliella tertiolecta（DT) and their industrial by products，Dunaliella tertiolecta residues（DTR) into bio-oils（MO-1,MO-2)in the presence of water at high temperature（about 320-360℃) and high pressure（about 20MPa). The experimental results show that the yield of bio-oils was significantly influenced by the chemical components of raw materials. These algae biomass with high crude fat content are beneficial to product bio-oils. The detailed compositional analysis of bio-oils was carried out by Elemental analyzer，Fourier transform infrared spectroscopy（FT-IR) and gas chromatography-mass spectrometry（GC-MS). The empirical formula of oil MO-1 and oil MO-2 with a heating value of 26.62 MJ/kg and 30.74 MJ/kg were established as CH1.38O0.43N0.07 and CH1.44O0.29N0.05，respectively. The analytical results also show the most components in the hexane fraction separated from the oil MO-1 are hexadecanoic acid and palmitamice，however，Oil MO-2 contains mostly compounds including benzofuranone，octadecadi enoic acid，palmitic acid methyl ester and paimitamide.
