Abstract (en)
A refined oil is obtained by using a heavy oil having a hydrogen content of 12 wt% or less as a feed oil, and after carrying out a solvent extraction process such that the hydrogen content increases by 0.2 wt% over that of the feed oil, hydrorefining process is carried out such that the hydrogen content increases by 0.5 wt% over the extracted oil. Thereby, an inexpensive heavy oil can be used as a feedstock, and using a simple and reliable method, refined oil can be produced.
