Adsorptive desulphurization has been one of the focus of the researchers over the past decade due to its lower energy consumption, environmentally friendly, and cheaper alternative. In this study, bentonite-based adsorbents are used to reduce the concentration of dibenzothiophenes in the model oil. Five different kinds of bentonite-based adsorbents; pure bentonite, acid-washed bentonite, Ni-bentonite, sodium-bentonite, and magnesium-bentonite, were prepared. These five bentonite-based adsorbents were tested under normal ambient conditions, and the result showed that Ni-bentonite has the highest desulphurization at 49.8%. Then, Ni-bentonite was tested in two different ranges DBT concentration; 100 ppm and 1000 ppm. The result shows that Ni-bentonite performed poorly in 100 ppm DBT model oil. Therefore, 1000 ppm of DBT model oil is chosen instead. Then, Nickel-bentonite is subjected to different parameters tests. In the effect of adsorbent dosage study, the result showed that the optimum desulfurization of Ni-bentonite dosage is 1.0 g. For the effect of temperature study, the result showed that the optimum temperature for desulphurization is 40°C. Regarding the effect of contact time between the adsorbent and adsorbate, the result showed that the optimum contact time for desulphurization 2 hours. The last parameter tested is the effect of the percentage of metal loading. The result showed that 30% of nickel loading provides the highest desulphurization percentage, at 55%. In the present study, the adsorption process was found to fit the Langmuir isotherm model better than Freundlich isotherm.
