“…Note also that for some fractions obtained by rectification, the boiling points have been determined from measured vapor pressure curves as well [17]. For simple batch distillation narrow boiling range fractions, average boiling points were not given as the above approach is not reliable for simple batch distillation (more specifically, without an empirical correcting equation [11]), although the initial and final collecting temperatures of fractions were recorded [18].…”

The evaluation of experimental data is based on the disclosure of essential information related to data measurement. A recent paper published in the journal Oil Shale presented experimental viscosity data on narrow boiling range fractions, prepared by distillation from a wide gasoline fraction of Kukersite oil shale pyrolysis oil (from an industrial plant). However, the article suffers from a deficiency of experimental description coupled with somewhat of an oversimplification of derivation of viscosity data from capillary viscometer measurements. Therefore, this addendum or short commentary supplemental article provides additional experimental information desirable for data evaluation and interpretation, along with corresponding corrections to the data.

“…However, most distillations were simple batch distillations that were carried out either at atmospheric pressure (using an Engler distillation [26]), and/or in a vacuum. Additional information on experimental settings and procedures can be found in: rectification [22,27] and simple distillation [23,28] of gasoline; rectification [27,29] and simple distillation [28] of fuel oil.…”

“…The average boiling points for the samples were measured by means of a thermogravimetric analyser based method [27][28][29]. The accuracy of this method was evaluated using measured oil narrow boiling range fractions that had been obtained by Rannaveski et al [27] according to the ASTM D2892 standard.…”

This article investigates a potential for using models based on infrared spectra to predict basic thermodynamic properties of narrow boiling range oil fractions or pseudocomponents. The work took advantage of the simultaneous availability of a property database of narrow boiling range fractions of Kukersite oil shale retort oil (from the industrial retorting process) together with infrared spectra of these fractions. The work was based on the hypothesis that the models based on infrared spectra could potentially be used to reduce experimental data when developing other predictive methods, or even as a substitute for other prediction methods. In this study four basic oil properties, which are often used to predict other thermodynamic properties, were predicted from infrared spectra using support vector regression. These were specific gravity, refractive index parameter, average boiling point and molecular weight. According to bulk property prediction approach these selected properties can be grouped into energy parameters (two former) and size parameters (two latter). It was found that, for distillation fractions with varying compositions, both the energy parameters (specific gravity, refractive index) as well as the size parameters (molecular weight, average boiling point) can be predicted from Fourier transform infrared (FTIR) spectra, and that the accuracy of the predictions based on infrared spectra was comparable with the accuracies of petroleum bulk property correlations. Thus, infrared spectra can provide a convenient alternative in the thermodynamic property prediction field because they can be easily measured and correlated to a wide variety of properties.

The recent paper "Viscosity data for kukersite shale gasoline fractions" [1], published in the scientific-technical journal Oil Shale by Baird and co-workers, presented experimental viscosity data on narrow boiling range fractions, prepared by distillation from a wide gasoline fraction of Kukersite oil shale pyrolysis oil (from an industrial plant). However, the article suffers deficiency of experimental description together with somewhat of an oversimplification of derivation of viscosity data from capillary viscometer measurements. Therefore, this short commentary supplemental article (i.e. addendum) provides additional experimental information desirable for data evaluation and interpretation, along with corresponding corrections to the data.
