    Abstract: The present disclosure provides a method for refining waste plastic pyrolysis oil, the method including: a first step of mixing a dechlorinating solution containing a polar aprotic solvent and water and waste plastic pyrolysis oil to form a mixed oil; a second step of allowing the mixed oil in the first step to stand and separating the dechlorinating solution located at a lower portion to obtain pre-treated waste plastic pyrolysis oil; a third step of performing a dechlorination reaction by hydrotreating the pre-treated waste plastic pyrolysis oil in the second step at a first temperature in the presence of a hydrotreating catalyst; and a fourth step of performing a denitrification reaction by hydrotreating a product produced in the third step at a second temperature in the presence of a hydrotreating catalyst.

    Abstract: Embodiments of the present disclosure provide a method for producing synthetic fuel from water and carbon dioxide. The method includes the operations of (a) preparing water-derived hydrogen, (b) preparing carbon dioxide, (c) introducing the hydrogen and carbon dioxide into a first reaction to produce a first product comprising synthesis gas, (d) introducing the synthesis gas into a second reaction to produce a second product comprising syncrude, (e) dividing the syncrude oil into a plurality of fractions comprising a first fraction, (f) introducing at least one fraction of the plurality of fractions into a hydrogenation reaction to produce a third product, and (g) recovering a fraction corresponding to a boiling point range of the first fraction from the third product. The present disclosure also provides an aviation fuel produced by the method.
