Abstract
A method for refining fuel oil comprises subjecting fuel oil to an extraction treatment with an extraction agent to extract a light component from the fuel oil, so as to obtain a light oil mixture containing the light component of the fuel oil and the extraction agent. The extraction agent is selected from the group consisting of a matter composed of oil and miscible with the light component of the fuel oil, a non-polar compound in a gaseous state at the room temperature and atmospheric pressure, and a combination thereof. The extraction agent is in a liquid state during the extraction treatment.

A method for refining fuel oil, comprising:
- subjecting fuel oil to an extraction treatment with an extraction agent to extract a light component from the fuel oil, so as to obtain a light oil mixture containing the light component of the fuel oil and the extraction agent,
- wherein the extraction agent is a matter composed of oil and miscible with the light component of the fuel oil, the matter composed of oil and miscible with the light component of the fuel oil including a hydrocarbon, a number of carbon of which ranges from 5 to 20, the matter composed of oil and miscible with the light component of the fuel oil being selected from the group consisting of diesel, gasoline, kerosene, and combinations thereof,
- wherein the extraction agent is in a liquid state during the extraction treatment, and
- wherein the extraction treatment is conducted at an atmospheric pressure and a temperature ranging from 25° C. to 100° C. under centrifugation.
