Study on two-step hydrothermal liquefaction of macroalgae for improving bio-oil
Abstract
In this work, the conversion of Enteromorpha clathrata into bio-oil through hydrothermal liquefaction (HTL) was investigated under different preparation conditions. A two-step reaction method was compared with single-step reaction. At a high temperature, bio-oil produced through the two-step hydrothermal reaction displayed slight changes in yield, but solid residue rate was low. The liquid-to-material ratio of the optimal preparation condition was 40/4 (mL/g). Bio-oil produced in each experiment at this ratio was further analyzed using GC/MS. Furthermore, density functional theory (DFT) quantitative calculation was used in analyzing and proving the possible reaction path of the conversion of furan compounds to aromatic compounds during a direct high-temperature liquefaction process. Results revealed that the two-step method can ensure a high bio-oil yield, while preventing the occurrence of side reactions caused by long-term high-temperature reactions, and improve the bio-oil quality.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
