汽柴油脱硫技术研究进展及发展趋势

Advances and development in desulphurization of gasoline and diesel

介绍了国内外现有汽柴油脱硫技术的研究进展,并结合其研究或应用的实际特点及目前脱硫技术研究存在的问题,讨论了今后国内外脱硫工艺的发展方向。提出的液相氧化脱硫工艺的脱硫率高,适用于高沸点的重质油脱硫,并且其无负面影响,分离得到的油及硫化物都具有高附加值,该方法预计会发展成为一种新型的环保脱硫技术。

This status quo of the existing gasoline and diesel desulfurization technology at home and abroad were introduced, and it’s future development direction was disscussed, in the basis of combination with the actual characteristics of the research or application and the problems in the present research. This paper also makes a point that the desulfurization rate of liquid phase oxidation is high and suitable for heavy oil with high boiling point. Without negative impact, this method could get oil and sulfide with high added value. It is foreseen that liq-uid phase oxidation for desulfurization would be a new environmental protection desulfurization technology.
