Özet
In this research, desulphurization of number 6 fuel oil (residue fuel oil) by chemical methods was studied. Besides, factors like reaction temperature, reaction time, concentration, and stirring speed were examined to determine the effects of various process parameters on desulphurization and on higher heating value. According to the results obtained, the optimum values of process parameters were determined as H2O2 concentration of 15%, reaction temperature of 40 degrees C, reaction time of 60-150 min and stirring speed of 1,000 rpm. Under these conditions, the sulphur content in the fuel oil sample was reduced from 2.78 to 2.29%-1.54% approximately. The degree of desulphurization increased, but higher heating value decreased seriously at high levels of H2O2 concentration, reaction temperature, reaction time, and stirring speed. Some fuel oil samples that are pretreated with H2O2/0.1 N H2SO4 were extracted successively with acetone, ethanol, ethylene glycol, and hydrogen peroxide. In conclusion, the sulphur content decreased approximately from 2.29 to 1.08%. Partial decrease determined in the higher heating value of the sample at the end of extraction.
