Experiment-related comments and corrections to the article "Viscosity data for kukersite shale gasoline fractions"

Abstract

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.
