In many works, simple batch distillation has been used to fractionate shale oils to narrow boiling range fractions and it has been attempted to calculate average boiling points of fractions as arithmetic averages of the initial and final temperatures of the thermometer during fraction collection [12, 13].
In some cases, a distilled gasoline boiling range material was not available, and we assumed that process conditions could be adjusted to produce a product meeting the T90 limit.
Desulfurization proceeds due to crude oil properties mainly high boiling range, high fluidity, high sulfur content and nat ure of sulfur content.
A refining process using controlled heat and pressure with catalysts to rearrange certain hydrocarbon molecules, thereby converting paraffinic and naphthenic type hydrocarbons (e.g., low-octane gasoline boiling range fractions) into petrochemical feedstocks and higher octane stocks suitable for blending into finished gasoline.
