“…A destilação simulada tem como premissa básica o fato de que os componentes da amostra analisada eluem da coluna cromatográfica em ordem crescente de pontos de ebulição 2,29,30 . Isso é normalmente obtido para hidrocarbonetos através do uso de fases estacionárias apolares, como as metil-polisiloxanas e as 5%-fenil-metilpolisiloxanas 17 .…”

Recebido em 7/6/04; aceito em 15/10/04; publicado na web em 17/2/05 SIMULATED DISTILLATION IN THE PETROLEUM INDUSTRY. One of the most widely used physico-chemical characterizations of hydrocarbon mixtures is the determination of their boiling point distribution. Knowledge of the boiling range of crude oils and petroleum products is essential to ensure the correct specification of final products and to control refinery processes. Simulated distillation, a GC based process, has been playing this role for the past decades in the petroleum industry. The main purpose of this work is to show the fundamentals of this technique as well as its present trends.

“…Through this calibration curve, simdist gives the hydrocarbon distribution of the sample (expressed in weight percent) versus the boiling range of the fraction (expressed in Atmospheric Equivalent Boiling Point or AEBP). The conditions used for simdist, the choice of both the column and the experimental conditions [2][3][4][5] are tuned to provide results in agreement with preparative distillation that gives the TBP curve (as described in ASTM D2892). The first methods were originally developed for gasoline (ASTM D3710 [6]).…”

“…Simdist was allowed up to 575°C using an internal standard for the quantification of the heavy fraction. In the 90's, new analytical approaches have been implemented to deal with the heavy ends: wide bore capillary columns have been introduced [10] and new thermally-stable capillary columns [4,11] with aluminum or stainless steel coating for performing high-temperature GC (HTGC). Normal paraffin with 100 carbons was eluted using a final oven temperature of 430°C [10].…”

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 distribution des hydrocarbures d'un échantillon (en % poids) en fonction du point d'ébullition de cette fraction. Les conditions expérimentales de la distillation simulée sont ajustées pour obtenir des résultats en accord avec les méthodes de distillation physiques qui fournissent la température d'ébul-lition vraie. Cependant, cette technique n'est pas compatible avec les fractions lourdes (point final supérieur à 700°C) en raison de la limitation de la volatilité et du manque de résistance des composés de haut poids moléculaire envers les réactions de craquage. L'intérêt de la chromatographie en phase supercritique (CPS) réside dans le fait que les hautes températures ne sont pas requises et que le mécanisme pour étendre la limite supérieure de la courbe de distillation dépend de la solubilité de l'échantillon dans la phase supercritique. Cet article présente des avancées récentes en distillation simulée basée sur la CPS. Comparativement à la CPG, la CPS étend la gamme de cette application jusqu'au nC 126 et rend possible une extrapolation jusqu'au nC 200 . Par conséquent, la CPS est un outil de choix pour obtenir une meilleure quantification de la conversion des fractions pétrolières lourdes. Abstract -Extended Simulated Distillation by Capillary Supercritical Fluid ChromatographySimulated distillation (simdist) based on separation using gas chromatography (GC) is widely spread in the petroleum industry for evaluation of fossil fuels as well as petroleum feeds and cuts produced by refining and conversion processes. Through a calibration curve relating the boiling point of normal paraffins to their elution temperature or retention time, simdist provides the hydrocarbon distribution of the sample (in weight percent
