Sažetak
Liquid–liquid extraction is one of the alternative methods that can be used for denitrification of FCC gasoline and diesel fuel. Extraction with ionic liquids as selective solvents makes the separation process ecologically acceptable due to the nonvolatility of ionic liquids as well as their complete regeneration. Liquid–liquid equilibrium for the systems hydrocarbon – pyridine – C6mmpyTf2N has been experimentally determined at the atmospheric pressure and 25 °C. Three paraffin hydrocarbons (n-hexane, n-heptane and i–octane) and one aromatic hydrocarbon (toluene) have been selected, since FCC gasoline consists mostly of paraffins. Toluene was selected because aromatic hydrocarbons are soluble in ionic liquids as well, and pyridine is a representative of nitrogen compounds. Besides the equilibrium curves, the tie lines were determined experimentally as well. Equilibrium data were described with NRTL and UNIQUAC models. Distribution coefficients and selectivities of ionic liquid were evaluated. Both of them decrease with increasing concentration of pyridine. The extraction efficiency is higher for the three-component systems with paraffins. For the model solution which consists of all selected compounds plus thiophene a decrease in extraction efficiency was observed with respect to three-component systems.
