Hydrothermal Liquefaction of Wheat Straws for Bio-Oil and Related Analyses
The liquefaction of wheat straws in sub-critical water to obtain bio-oil was investigated in this paper. We observed that the reaction temperature (300-374 °C) and reaction time (1-15 min) played important roles in the yield of bio-oil and found the optimal reaction conditions (340 °C, 5 min). The bio-oil was analyzed by elemental analysis, the Fourier transform infrared spectroscopy (FTIR) and gas chromatography-mass spectrometry (GC-MS). Results indicated that the heating value of bio-oil product was 32-38 MJ/kg, higher than that of the bio-oil obtained from microalgae, and the product was composed of ketones, phenol and its derivatives, aromatics and small amount of aldehydes and ethers.
