- 摘要：
- Herein, we report on a combined process that incorporates hydrothermal liquefaction (HTL) and supercritical
water gasification (SCWG) to improve energy recovered from algal biomass. Eight algal biomasses,
including four microalgae and four macroalgae with a large difference in biochemical
compositions, were screened for this dual process. The algal biomass feedstocks significantly affected the
carbon and energy distribution in the product fractions (crude bio-oil, solid, gas, and water-soluble
products). 62.50e71.34% energy of microalgae and 6.03e41.06% energy of macroalgae could be recovered
as crude bio-oil. 11.86e21.55% carbon of the microalgae and 8.01e15.82% carbon of the macroalgae
was distributed in the HTL process water in form of water soluble products after the HTL process. 14.3
e33.7% energy of microalgae and 30.18e36.34% energy of macroalgae was retained in the HTL process
water. SCWG could convert the organics in the HTL process water into fuel gases consisting mainly of H2
and CH4. 54e91% carbon of the HTL process water was transformed into the fuel gases, which correspond
5.53e18.30% energy of the algal biomass. Thus, this work shows that the integration of HTL and SCWG
could improve energy recovery from algal biomass relative to the HTL process alone.
