Abstract: Research progress of applications of heteropoly acid catalyst in the oxidative desulfurization of fuel oil was introduced. Heteropoly acid catalysts，including those containing transition metal，alkali metal，rare earth metal，quaternary ammonium salt，ionic liquid and catalysts supported on carriers，such as carbon materials，titanium dioxide，silica，polymer materials were described and the characteristics and catalytic effects of the catalysts were summerized.Comprehensive utilization of heteropoly acid catalysts’ properties and the development of novel high performance heteropoly acid catalysts with high activity，less oxygen consumption and strong reusability were important research topics for deep desulfurization through catalytic oxidation.

Key words: heteropoly acids, desulfurization, catalytic oxidation
