Extended Simulated Distillation by Capillary Supercritical Fluid Chromatography

Abstract: Résumé -Distillation simulée étendue par chromatographie en phase supercritique -La distillation simulée (simdist) fondée sur une séparation par chromatographie en phase gazeuse (CPG) est largement répandue dans l'industrie pétrolière afin d'évaluer les huiles comme les charges et recettes des procédés de raffinage et de conversion du pétrole brut. Grâce à une courbe de calibration reliant le temps de rétention à la température d'ébullition de paraffines normales, la distillation simulée fournit la distributio… Show more

“…Evaluation of the boiling point curves for the samples have been determined on a phenol-free basis, because of the hindrance of the phenol peak that masks other peaks. The lightest compounds (i.e., naphtha) with a boiling point distribution of 79–191 °C were coeluted with the solvent elution peak, as inferred from the excessive broadening of the solvent boiling point peak . From Figure , it is observed that the HS fraction generated at 300 °C yielded the highest boiling point distribution, with regard to constant recovered mass, followed by HS compounds generated at 320, 340, and 360 °C.…”

“…The lightest compounds (i.e., naphtha) with a boiling point distribution of 79−191 °C were coeluted with the solvent elution peak, as inferred from the excessive broadening of the solvent boiling point peak. 50 From Figure 10, it is observed that the HS fraction generated at 300 °C yielded the highest boiling point distribution, with regard to constant recovered mass, followed by HS compounds generated at 320, 340, and 360 °C. However, at 500 °C and above, this trend is no longer observed, as shown in Figure 10.…”

“…Light aromatics containing heteroatoms could be distilled off with this fraction. The split between alkanes and aromatics could be performed using supercritical fluid chromatography by changing the solvent strength (Dulaurent et al, 2007).…”

“…It must be pointed out that the elution of heavier hydrocarbons would require at the same time higher temperatures (ca. 160°C) and backpressures to be applied as it has been described elsewhere using capillary or packed column SFC for simulated distillation purpose 9, 24. At such temperatures, high backpressure is necessary to keep the density at a quite high value (ca.…”
