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
