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%。

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%.
