Researchers used H2O2 and H2SO4 solutions to remove sulfur from high-sulfur No. 6 fuel oil. They tested different concentrations and found that H2O2 leaching was the most effective method. The best results were achieved with H2O2/0.1N H2SO4 leaching. Optimal parameters for H2O2 leaching were 15% concentration, 30°C temperature, and 60 minutes reaction time. For H2SO4 leaching, the best parameters were 0.1 N concentration, 30°C temperature, and 150 minutes reaction time. Increasing temperature, time, and concentration decreased carbon and hydrogen content but increased oxygen content. The study was supported by Inönü University's Scientific Research Projects Unit.
