- 摘要：
- Hydrothermal liquefaction using eight algal biomasses was performed at 350 °C for 1 h. The microalgae
always produced a higher crude bio-oil yield than the macroalgae due to their high lipid content, among which Schizochytriumlimacinum provided the maximum crude bio-oil yield of 54.42 wt%. For microalgae, higher amounts of N in the biomass resulted in higher amounts of N in the crude bio-oil; however, contrary results were observed for the
macroalgae. The crude bio-oils generated from both the microalgae and macroalgae were characterized as having a
high viscosity, total acid number, and heteroatom content, and they were influenced by the biochemical compositions
of the feedstocks. Next, all eight-crude bio-oils were treated at 400 °C for 2 h with 10 wt% Ru/C using tetralin
as the hydrogen donor. The hydrogen source was provided after tetralin was transformed to naphthalene. All the
upgraded bio-oils had higher energy densities and significantly lower N, O, and S contents and viscosities than their
corresponding crude bio-oils. However, the H/C molar ratio of the upgraded bio-oils decreased due to the absence of
external hydrogen relative to the crude bio-oils. The S content of the upgraded bio-oil produced from upgrading the
Schizochytrium limacinum crude bio-oil was even close to the 50 ppm requirement of China IV diesel.
