Abstract: Sulfur removal using adsorption requires a proper process parametric study to determine its optimal performance characteristics. In this study, response surface methodology was employed for sulfur removal from model oil (dibenzothiophene; DBT dissolved in iso-octane) using commercial activated carbon (CAC) as an adsorbent. Experiments were carried out as per central composite design with four input parameters such as initial concentration (C0: 100-900mg/L), adsorbent dosage (m: 2-22g/L), time of adsorption (t: 15-735min), and temperature (T: 10-50°C). Regression analysis showed good fit of the experimental data to the second-order polynomial model with coefficient of determination R2-value of 0.9390 and Fisher F-value of 16.5. The highest removal of sulfur by CAC was obtained with m=20g/L, t=6h, and T=30°C. © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
