Kinetic parameters
The values of the kinetic parameters and the individual error estimates
for the nonlinear kinetics of hyperbolic and pseudo second order models
are presented in Table 1. In Table 1, it could be observed that majority
of the kinetic parameters of C1 and Csfor hyperbolic and Pseudo second order models, respectively, increased
with the increase in temperature. This could be attributed to the reason
behind the increase in the oil yield as temperature increased
[18,42]. Similarly, the kinetic parameters of C2 and
K also increased with increase in temperature as could be observed in
Table 1. This increase in oil yield with temperature was as a result to
the thermodynamic effect of oil solubilization inside the solid seed
particles [32]. The observations in the kinetic parameters of the
hyperbolic and Pseudo second order models, were in line with the results
obtained by Kitanovic et al. [19] and Agu et al. [56] for the
solvent extraction of resinoid from aerial part of Hypericum
perforatum L and extraction of oil from Colocynthis vugaris
Shrad seed, respectively.
