摘要：
Oxidative desulfurization of hydrodesulfurized diesel using aldehyde and molecular oxygen in the presence of cobalt catalysts was studied. Among the catalysts used, cobalt phthalocyaninetetrasulfonamide was found to be the most efficient catalyst for the oxidation of sulfur compounds present in diesel. The reactivity of 4,6-dimethyldibenzothiophene is greater compared to 4-methyldibenzothiophene. Sulfur content in diesel was reduced from 448 to 41 ppm by oxidation followed by extraction with acetonitrile. It was further reduced to 4 ppm by passing through a silica gel column.
