Abstract The non-hydrogen-reducing desulfurization methods have been developing all over the world in order to meet the diesel oil sulfur-containing standards that become more and more rigorous.Though TS-1,one of diesel oil catalytic oxidation desulfurization catalyst,can attain a good result of desulfurization,its dosage is too high to inconvenience to the operation.Introducing formic acid and acetic acid as catalyst-accelerators,and their effects on its capability were examined.The research showed that owing to the add of these two additives,the dosage of TS-1 can be redeuced to 50 percents and 6111 percents respectively and the desulfurization ratio reached to 1563 percents and 1811 percents respectively.The accelerators improve both the capability and activity of the TS-1 catalyst.Consequently,after desulfurization,the amount of the sulfur in the diesel fuel suffices for the Europe Ⅱ# diesel standard (<300μg/g).
