Beschreibung
Zusammenfassung:	The present invention relates to a method for producing very low-sulfur fuel oil having high compatibility and high stability, comprising: mixing petroleum residua obtained from at least two different petroleum refining processes, adding a hydrocarbon solvent to the residual petroleum mixture, heating the mixture of the petroleum residua mixture and hydrocarbon solvent to extract and recover a mixture of oil fractions and the hydrocarbon solvent from the mixture of the petroleum residua mixture and hydrocarbon solvent with raffinate having asphaltenes therein being left, and removing the hydrocarbon solvent from the mixture of the oil fractions and the hydrocarbon solvent, thereby obtaining very low-sulfur fuel oil, wherein the very low-sulfur fuel oil has a sulfur content of 0.5 wt % or less bared on the total weight of the very low-sulfur fuel oil, and very low-sulfur fuel oil produced by the production method.
