Optimization analysis of mixing-assisted oxidative desulfurization of model sulfur compounds using commercial ferrate(VI)
Abstract: Mixing-assisted oxidative desulfurization of benzothiophene (BT) and dibenzothiophene (DBT) was investigated using commercial ferrate(VI). The effect of operating parameters such as temperature (50–70°C), agitation speed (7,600–14,000 rpm), and mixing time (10–30 min) were examined in rela...

| Summary: | Abstract: Mixing-assisted oxidative desulfurization of benzothiophene (BT) and dibenzothiophene (DBT) was investigated using commercial ferrate(VI). The effect of operating parameters such as temperature (50–70°C), agitation speed (7,600–14,000 rpm), and mixing time (10–30 min) were examined in relation to sulfur reduction. Optimization experiments were carried out using Box–Behnken design under response surface methodology to evaluate the significance of operating variables. Results show that optimum sulfur reduction of 84.35% for BT could be attained at 15.42 min, 12,198 rpm, and 52.22°C. Moreover, a 93.68% sulfur reduction for DBT could be achieved at 14.43 min, 8,704 rpm, and 51.26°C. Using the optimized conditions, diesel oil was oxidized and showed a sulfur reduction of 58.03 and 93.15% for BT and DBT, respectively. © 2015 Balaban Desalination Publications.
