Elisa Reis Paz, Lucas Farias Falcchi Corrêa, Roberta CerianiAlthough petroleum is widely used to make solvents and
to produce
energy, solvents derived from it, such as acetonitrile, may not be
the safest and most sustainable options currently available. Additionally,
processes such as the Fischer–Tropsch synthesis emerge as an
intelligent alternative to produce energy from coal, biomass, or natural
gas to supply the increasing demand for petroleum-derived products.
Thus, with a green solvent, γ-valerolactone, applied to the
removal of oxygenated compounds from a Fischer–Tropsch process
stream, this work suggests the application of a less toxic solvent
to an alternative energy production process through model systems.
In this sense, liquid–liquid equilibrium experimental data
were measured for systems composed of an oxygenated solute (1-heptanol,
propanone, 2-butanone, or 2-heptanone) + γ-valerolactone + n-tetradecane at 298.15 K. The liquid–liquid equilibrium
data were successfully correlated by the nonrandom two-liquid model
with a medium average deviation lower than 1%. Therefore, the measured
experimental data may contribute to the design of a liquid–liquid
extraction process applied to the refinement of synthetic crude oil
from a Fischer–Tropsch synthesis.
