n response to stringent regulations aimed at preventing
environmental pollution, nitrogen- containing impurities
have to be removed from transportation fuels, including
gasoline. In this context, deep eutectic solvents (DES) have
been recently identified as credible green candidates for
denitrogenating liquid fuels. In this work, the ability of choline
chloride/ glycerol DES as a denitrogenation solvent for model
gasoline was investigated at 295.15 K and atmospheric
pressure. Experimental liquid-liquid equilibrium data for
heptane + pyridine or quinoline + choline chloride/glycerol
DES were determined using the equilibrium cell method.
Heptane served as a model for gasoline while nitrogen-
containing impurities consisted of pyridine and quinoline.
Choline chloride/glycerol DES showed greater extraction
potential for pyridine than quinolone. However, calculated
selectivities and distribution coefficients indicated that the
studied DES is a promising denitrogenation agent in both
cases. Subsequently, the experimental data were successfully
correlated by means of the non-random two-liquid (NRTL)
model. The root mean square deviations (RMSD) between
calculated and experimental compositions were 0.0457 and
0.0458 for heptane + pyridine + choline chloride/glycerol
DES and heptane + quinoline + choline chloride/glycerol DES,
respectively.
