The invention provides a method for desulfurization of hydrogenated fuel oil. The method is characterized in that sulfur trioxide is first added or introduced into the hydrogenated fuel oil so that the hydrogenated fuel oil and sulfur trioxide are mixed fully, the hydrogenated fuel oil obtained after mixing contact is completed is converted hydrogenated fuel oil, then the converted hydrogenated fuel oil is in contact with a polar solvent which repels the fuel oil and is adopted as extractant, and final desulfurized hydrogenated fuel oil is obtained after extractive desulfurization operation isperformed. 本发明提供种加氢燃油脱硫方法，其特征在于：首先将三氧化硫加入或通入到加氢燃油中，使加氢燃油与三氧化硫进行充分的混合接触，混合接触结束后的加氢燃油即为转化处理过的加氢燃油；然后将转化处理过的加氢燃油与作为萃取剂的不与燃油相溶的极性溶剂相接触，进行萃取脱硫操作后即获得最终的脱硫加氢燃油。
