چکیده انگلیسی
The production of bio-oil and bio-char by fast pyrolysis and hydrothermal liquefaction of Enteromorpha clathrata, rice husk and their mixtures have been compared. The results indicated that hydrothermal liquefaction produced higher yield of bio-oil and lower yield of bio-char for the same raw samples. There were more macromolecules (hexadecanoic acid, cyclopenten and esters), small-molecule hydrocarbons and N-containing compounds in hydrothermal liquefaction bio-oil, while more aromatic substances were observed in fast pyrolysis bio-oils. There was significant difference between E. clathrata bio-oils from these two thermochemical methods CO, CH/CH2/CH3 and NH functional groups in E. clathrata bio-oil from hydrothermal liquefaction showed stronger absorption strength than bio-oil from fast pyrolysis. However, the only difference between rice husk bio-oil from hydrothermal liquefaction and fast pyrolysis was aromatic ring signal in Fourier transform infrared spectroscopy curves. In addition, synergistic effect was investigated during the co-pyrolysis and co-hydrothermal processes. Such synergistic effect led to the improvement recorded in the bio-oil quality by deoxidation reaction to increase the H/C ratio in bio-oil from co-pyrolysis of E. clathrata/rice husk blends, and reduces the O/C ratio in bio-oil from co-hydrothermal process, and also enhances the calorie value of bio-oil. The synergistic effect, however, lowered the co-pyrolysis and co-hydrothermal bio-oils yields. Moreover, the addition of rice husk into E. clathrata promoted the bio-oil conversion efficiency of protein and increased the content of aromatic substances.
