| 摘要 |
A method for purifying a sulfur-containing fuel oil comprising (a) contacting in a first reaction mixture the sulfur-containing fuel oil with an exogenous binary catalyst, hydrogen peroxide, and a water-soluble acid at a temperature in a range of from about 25° C. to about 150° C. to provide a first oxidized mixture; and (b) separating at least one oxidized sulfur compound from the first oxidized mixture to provide a purified fuel oil. The first reaction mixture may further comprise a phase transfer catalyst. Furthermore, the sulfur-containing fuel oil may be deasphalted prior to contacting with the catalyst, hydrogen peroxide, and the water-soluble acid.
