Effects of Extraction on the Desulfurization of
FCC Diesel by Ultrasound Oxidation Technique

Abstract
Sulfide removal from FCC diesel fuel is a
critical issue. Researchers removed
sulfides by catalytic oxidation, transforming them into sulfones by H2O2-formic
acid and solvent extraction induced by ultrasound irradiation.
The introduction of ultrasound provides energy
for the oxidation reaction, which can assure a complete oxidative
desulfurization for sulfides in diesel oil. The effects of extraction solvent,
extraction duration, ratio of extractant over extraction times, and oil over
extraction times were investigated.
