PROBLEM TO BE SOLVED: To provide a practical method of adsorptive desulfurization, capable of selectively and efficiently adsorbing/removing organic sulfur compounds included in coal-based heavy oil.SOLUTION: Sulfur compounds included in coal-based heavy oil can be selectively and efficiently adsorbed/removed by treating the coal-based heavy oil with a metal-loaded adsorbent carrying a metal such as Pt, Pd or the like with a carrier such as alumina, silica, etc., in an organic solvent capable of dissolving the coal-based heavy oil, such as tetrahydrofuran, etc., in the presence of hydrogen. |
