Abstract:
The removal of sulfur-containing compounds from diesel fuel is a great problem in refinery industry.In the world, the goal for super low desulfurization clean fuel oil (sulfur content <10 μg8226;g-1) has been put forward.In this paper, by using continuous extraction-photocatalytic oxidation desulfurization process, the technology for refining FCC diesel fuel by removing sulfurcontaining compounds was investigated.Sulfur content was analyzed by Anteck Analyzer .Sulfur content of refining oil 45 μg8226;g-1 met Europe Ⅳ standard.The experiment results showed that the suitable conditions of extraction and reaction were normal atmosphere, temperature 40℃,solvent/oil ratio 1.5∶1;temperature 40℃, residence time 1 h,and oxidant use 4%.Under these conditions, total sulfur content of two types of FCC diesel fuel met Europe Ⅳ standard, and refined oil yield was above 96%.

摘要:
尽快降低燃料油中的硫含量是整个炼油业都无法回避的重大问题,炼油工业发达的国家已提出生产超低硫清洁燃料 (硫含量低于10 μg8226;g-1)的目标。本文通过连续式FCC柴油萃取-光催化深度脱硫工艺,对FCC柴油进行精制,精制油中硫含量采用硫氮荧光分析仪测定,硫含量为45 μg8226;g-1。实验结果表明:萃取操作的适宜条件为常压,萃取温度40℃,剂油比1.5∶1;反应操作的适宜条件为反应温度40℃,反应时间1 h,氧化剂用量为4%。在以上操作条件下,精制油中的硫含量为达到欧Ⅳ标准,精制油总收率超过96%。
