燃料油氧化脱硫研究进展

脱硫技术已成为国内外提高燃料油质量的关键因素。传统加氢脱硫技术（HDS）虽然能达到深度脱硫的目的，但耗氢量大、设备投资大、操作费用高，难以满足低硫清洁燃料油的生产需要；氧化脱硫技术（ODS）因其在较温和的条件下即可得到超低硫燃料油而引起人们的广泛关注。简单介绍了氧化脱硫机理。重点概述了H2O2氧化法、分子氧氧化法、有机过氧化物氧化法、高铁酸钾氧化法脱除燃料油中噻吩类硫化物的最新研究成果。并分析了各种方法的优缺点。

Research Progress on Oxidative Desulfurization of Fuel Oils

The desulfurization technology has become the key factor of improving the fuel oils quality at home and abroad. Although traditional hydrogenation desulfurization（HDS） can achieve the purpose of desulfu- rization,it is difficult to meet the needs of production of low sulfur and clean fuel oils because of larger con- sumption of hydrogen, bigger equipment investment, higher cost of operation. Oxidative desulfurization（ODS） can get ultra-low sulfur fuel oils under mild conditions. The mechanism of oxidative desulfurization was intro- duced. The latest research of H2O2 oxidation, molecular oxygen oxidation,organic peroxide oxidation and potas- sium ferrate oxidation desulfurization technology were summarized in this paper. And the advantages and disad- vantages of different methods were analyzed.
