燃料油中噻吩类硫化物脱除技术研究进展

Technology progress in desulfurization of thiophene type sulfide in fuel oil

综述了燃料油中噻吩类硫化物脱除技术的研究进展。认为加氢脱硫技术存在投资大,运行成本高等问题;吸附、氧化、生物等非加氢脱硫技术将成为未来发展的趋势。离子液体脱硫技术将成为噻吩类硫化物非加氢脱除技术的研究热点,工业化前景广阔。

This paper summarizes that technology progress in removing sulfide with thiophene structure from fuel oil. Hydrogenation desulfurization technol- ogy has the problems including high equipment in- vestment and operation cost. Non - hydrogenation technologies, including desulfurization by adsorp- tion, oxidation and biological treatment, will become the future trend of development. Ionic liquids desul- furization technology will become a research focus in non - hydrogenation technologies of desulfurization of thiophene- type sulfide in oil and has broad in- dustrialization prospects.
