Abstract

Deep eutectic solvents (DES)/reduced graphene oxide (rGO) composite materials can remove dibenzothiophene (DBT) from fuel oil by adsorption desulfurization. However, the whole synthesis process is complicated, and the DES/rGO is high-cost and not strong enough, which limits its application in industry. Therefore, a one-step method to produce DES/rGO composite materials is proposed. The performance of desulfurization was studied and the feasibility of industrial application was analyzed. First, the proposed method can improve the single extraction efficiency to 94.8% without a complicated process. Secondly, the DES/rGO can also be reused and recycled. Third, the proposed method overcomes the inconvenient storage and transportation of liquid DES. Finally, the proposed method could effectively reduce the cost of desulphurization in the industry.

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.
