Title

DESULFURIZING A MODEL FUEL USING γAL2O3 AND NI/γAL22O3 ADSORBENTS AND DETERMINING THEIR CORRESPONDING ISOTHERMS

Pages

  51-64

Abstract

 In this work, ADSORPTION of 4, 6-DIMETHYLDIBENZOTHIOPHENE (4, 6-DMDBT) on Al2O3 and Ni/Al2O3 adsorbents from model diesel fuel (n-hexane-4, 6-DMDBT) is investigated in a batch system. At first, the best alumina is selected from four types of commercial alumina by ADSORPTION process in the batch system, and then to enhance the ADSORPTION capacity of alumina, its surface is modified with different percentages of nickel using wetness impregnation method. All ADSORPTION experiments are studied in batch systems and equilibrium data is obtained after 24 hours in each system. UV-visible spectroscopy is used to determine the ADSORPTION capacity, and XRD, XRF and nitrogen ADSORPTION- desorption analyses is used to characterize the adsorbents. The results indicate that the highest ADSORPTION capacity is obtained when 0.15 gram of nickel is loaded on 1 gram of alumina (0.15 gr Ni/gr Al2O3). ADSORPTION equilibrium data is fitted with Langmuir, Freundlich and Dubinin- Radushkevich isotherms and Langmuir isotherm is found to best describe the ADSORPTION process and predict maximum ADSORPTION capacity of 1.253 and 15.97 mg/g for Al2O3 and Ni/Al2O3, respectively.
